Question 51

In an election between two candidates, 8% of the votes were invalid. The winning candidate got 60% of the total valid votes and won the election by 5888 votes. How many voters were registered?

  1. AOption (a)

    29500

  2. BOption (b)

    33260

  3. COption (c)

    30000

  4. DOption (d)

    32000

View answer & explanation

Correct answer

Answer: (d)D.

32000

Why this answer is correct

Given:

8% of the votes are invalid

Winner got 60% of the valid votes

Winners won by 5888 votes

Calculation:

Let the total numbers of voters be 100a

Valid votes = 100a - 100a × 8%

⇒ 92a

Winning candidate got 92a × 60%

⇒ 55.2a

So, loosing candidate got = 92a - 55.2a

⇒ 36.8a

According to the question,

55.2a - 36.8a = 5888

⇒ 18.4a = 5888

⇒ a = 5888/18.4

⇒ a = 320

So, total voters registered = 320 × 100

⇒ 32000

∴ 32000 voters were registered.

Question 52

  1. AOption (a)

    ₹825

  2. BOption (b)

    ₹1,485

  3. COption (c)

    ₹859

  4. DOption (d)

    ₹1,584

View answer & explanation

Correct answer

Answer: (d)D.

₹1,584

Why this answer is correct

Given:

Yusuf purchased an item for Rs. 5500

Profit = 15% and 12%

Concept used:

SP = CP × (100 + P%)/100

Here, SP is selling price,, CP is cost price,, P% is profit%

Calculation:

The selling price of the item = (5500 × 115)/100

⇒ Rs. 6325

Yusuf purchases another item at Rs. 6325 

The selling price of the 2nd item = (6325 × 112)/100

⇒ Rs. 7084

Gain of Yusuf in the whole transaction = 7084 − 5500

⇒ Rs. 1584

∴ His overall gain is Rs. 1584.

  1. AOption (a)

    34 kg

  2. BOption (b)

    30 kg

  3. COption (c)

    44 kg

  4. DOption (d)

    32 kg

View answer & explanation

Correct answer

Answer: (a)A.

34 kg

Why this answer is correct

Given:

The average weight of X and Y is 40 kg

The average weight of Y and R is 62 kg

The average weight of X and R is 56 kg

Concept used:

Average = Sum of elements/Number of elements

Calculation:

Total of X and Y = 40 × 2 = 80 kg      ----(i)

Total of Y and R = 62 × 2 = 124 kg       ----(ii)

Total of X and R = 56 × 2 = 112 kg      ----(iii)

By adding eq (i), (ii), and (iii) we get

2(X + Y + R) = 316

⇒ X + Y + R = 158     ----(iv)

From eq (ii) and eq (iv) we can say

X = 158 - 124

⇒ 34 kg

∴ The weight of X is 34 kg.

Question 54

  2. BOption (b)

    14

  3. COption (c)

    10

  4. DOption (d)

    8

View answer & explanation

Correct answer

Answer: (a)A.

12

Why this answer is correct

Given:

Score of the 18th innings = 80

Average increased by 4

Concept used:

Average = Sum of elements/Number of elements

Calculation:

Let his average after 17th innings be X

Total runs after 18th innings = 17X + 80

According to the question,

[(17X + 80)/18] = X + 4

⇒ 17X + 80 = 18X + 72 

⇒ X = 8

So, average after 17th innings = 8

Now,

After 18th innings his average = 8 + 4

⇒ 12

∴ His average after the 18th innings is 12.

    ₹3,000

View answer & explanation

Correct answer

Answer: (b)B.

₹2,000

Why this answer is correct

Given:

Ratio of shares of X, Y, Z, and W = 5 : 2 : 4 : 3

Difference between Z and W = Rs. 1000

Calculation:

Let the amount X, Y, Z, and W get be 5x, 2x, 4x and 3x

Now,

According to the question,

4x - 3x = 1000

⇒ x = 1000

So, Y's share = 2 × 1000

⇒ Rs. 2000

∴ Y's share is Rs. 2000.

  3. COption (c)

    4.2 h

  4. DOption (d)

    4.8 h

View answer & explanation

Correct answer

Answer: (a)A.

4.4 h

Why this answer is correct

Given:

Speed of the two boys are 5.5 km/h and 3.5 km/h

Concept used:

Time = Distance/speed

Relative Speed of 2 bodies:

The relative speed of two objects = Difference in their individual speeds if they are moving in the same direction.

Calculation:

The relative speed of the two boys = 5.5 - 3.5

⇒ 2 km/h

Now,

Required time = 8.8/2

⇒ 4.4 hours

∴ They take 4.4 hours to be 8.8 km apart.

Additional InformationSpeed of the 1st boy is more than 2nd one

So, the distance between them after 4.4 hours will be 8.8 km.

  4. DOption (d)

    ₹1,600

View answer & explanation

Correct answer

Answer: (b)B.

₹1,000

Why this answer is correct

Given:

Ratio of shares of A, B, C, and D = 5 : 2 : 4 : 3

Difference between A and D = Rs. 1000

Calculation:

Let the amount A, B, C, and D get be 5x, 2x, 4x and 3x

Now,

According to the question,

5x - 3x = 1000

⇒ 2x = 1000

View answer & explanation

Correct answer

Answer: (c)C.

(1/V) = (2/S) (1/a + 1/b + 1/c)

Why this answer is correct

Given:

V and S denote the volume and Total Surface Area of a cuboid

Sides a, b, c

Concept used:

Volume of a cuboid = l × b × h

Total surface area = 2(lb + bh + lh)

Here, l = length, b = breadth, h = height

Calculation:

V = (a × b × c)

S = 2(ab + bc + ac)

Now,

From options:

Option 1:

1(a×b×c)=22(ab+bc+ac)×(a+b+c)\rm\frac{1}{(a × b× c)} = \frac{2}{2(ab + bc + ac)} × (a + b + c)

⇒ 1(a×b×c)=(a+b+c)(ab+bc+ac)\rm\frac{1}{(a × b× c)} = \frac{(a + b + c)}{(ab + bc + ac)}

Not satisfying

Option 2:

1(a×b×c)=2(ab+bc+ac)(1a+1b+1c)\rm\frac{1}{(a × b× c)} = 2(ab + bc + ac)(\frac{1}{a}+\frac{1}{b}+\frac{1}{c})

⇒ 1(a×b×c)=2(ab+bc+ac)(ab+bc+aca×b×c)\rm\frac{1}{(a × b× c)} = 2(ab + bc + ac)(\frac{ab+bc+ac}{a× b× c})

⇒ 1(a×b×c)=2(ab+bc+ac)2(a×b×c)\rm\frac{1}{(a × b× c)} = \frac{2(ab + bc + ac)^2}{(a× b× c)}

Not satisfying

Option 3:

1(a×b×c)=22(ab+bc+ac)×(1a+1b+1c)\rm\frac{1}{(a × b× c)} = \frac{2}{2(ab + bc + ac)} × (\frac{1}{a}+\frac{1}{b}+\frac{1}{c})

⇒ 1(a×b×c)=1(ab+bc+ac)(ab+bc+aca×b×c)\rm\frac{1}{(a × b× c)} = \frac{1}{(ab + bc + ac)}(\frac{ab+bc+ac}{a× b× c})

⇒ 1(a×b×c)=1(a×b×c)\rm\frac{1}{(a × b× c)} = \frac{1}{(a× b× c)}

Satisfying

Option 4:

(a×b×c)=22(ab+bc+ac)×(1a+1b+1c)\rm{(a × b× c)} = \frac{2}{2(ab + bc + ac)} × (\frac{1}{a}+\frac{1}{b}+\frac{1}{c})

⇒ (a×b×c)=1(ab+bc+ac)(ab+bc+aca×b×c)\rm{(a × b× c)} = \frac{1}{(ab + bc + ac)}(\frac{ab+bc+ac}{a× b× c})

⇒ (a×b×c)=1(a×b×c)\rm{(a × b× c)} = \frac{1}{(a× b× c)}

Not satisfying

∴ Required answer is Option 3.

Alternate Method 

V = abc

S = 2(ab+ bc +ca)

Hence, a = V/bc, b = V/ac, c = V/ab

S = 2(V/c + V/a + V/b)

S = 2V(1/a + 1/b + 1/c)

or (1/V) = (2/S) (1/a + 1/b + 1/c)

  4. DOption (d)

    108 days

View answer & explanation

Correct answer

Answer: (d)D.

108 days

Why this answer is correct

Given:

A can finish as much work in 6 days as C can in 8 days.

B can finish as much work in 6 days as C can in 4 days.

Concept used:

Total work = Efficiency of the worker × time taken by them

Calculation:

Let the efficiency of the A, B, and C be a, b, and c

According to the question,

6a = 8c

⇒ a/c = 8/6 = 4/3      ----(i)

Again,

6b = 4c

⇒ b/c = 4/6 = 2/3      ----(ii)

From eq (i) and eq (ii) we can say

a : b : c = 4 : 2 : 3

Let efficiency of them be 4x and 2x and 3x

Now,

Required work = 54 × 4x

⇒ 216x

Required time = 216x/2x

⇒ 108 days

∴ B will require 108 days to finish a work if A takes 54 days to finish it.

Why this answer is correct

Given:

Two numbers are 52 and 936

Concept used:

For this type of question we use LCM of the given number to calculate the required number

Calculation:

520 = 23 × 5 × 13

936 = 23 × 32 × 13

LCM = 23 × 13 × 32 × 5

⇒ 4680

So, required number = 4680 - 17

⇒ 4663

∴ Required number is 4663.

  4. DOption (d)

    156 cm2

View answer & explanation

Correct answer

Answer: (c)C.

154 cm2

Why this answer is correct

Given:

Sides of the rectangle = 15 cm and 7 cm

Concept used:

Perimeter of a rectangle = 2(l + b)

Perimeter of a circle = 2πr

Area of a circle = πr2

Here, l = length, b = breadth, r = radius

Calculation:

Let the radius of the circle be r

According to the question,

2(15 + 7) = 2πr

⇒ 2 × 22 = 2 × (22/7) × r

⇒ r = 22 × (7/22)

⇒ r = 7

So, the radius of the circle = 7 cm

Now, Area of the circle = (22/7) × 72

⇒ 22 × 7 = 154 cm2

∴ The area of the circle is 154 cm2.

  4. DOption (d)

    ₹1,50,000

View answer & explanation

Correct answer

Answer: (a)A.

₹1,20,000

Why this answer is correct

Given:

The difference between compound interest and simple interest on a certain sum at 10 percent per annum for 2 years is Rs. 1200.

Concept used:

Difference between compound interest and simple interest for 2 years:

Difference = P × (r/100)2

Here, P = principal or sum, r = Rate of interest

Calculation:

Let the sum be Rs. P

1200 = P × (10/100)2

⇒ 1200 = P × (1/10)2

⇒ 1200 = P/100

⇒ P = 1200 × 100 = Rs. 120000

∴ The sum is Rs. 120000.

Alternate Method

CI for 2 years at 10% = P(1 + r/100)2 - P

⇒ CI = P[(1 + 10/100)2 - 1]

⇒ CI = P[(11/10)2 - 1]

⇒ CI = P(121 - 100)/100

⇒ CI = 21/100 × P

SI for 2 years at 10% = (P × 10 × 2)/100

⇒ SI = 20P/100

Now, CI - SI = 1200

21P/100 - 20P/100 = 1200

P/100 = 1200

P = 120000

Hence, the sum is Rs. 120000.

Profit% = (240 − 150) ÷ 150 × 100 = 90 ÷ 150 × 100 = 60%.

∴ The correct answer is 60%.

Alternate Method

Given:

CP of milk = ₹50/litre | SP of mixture = ₹60/litre

Ratio of water to milk = 1 : 3

⇒ Let Milk = 3 units and Water = 1 unit

⇒ Cost Price (CP) = 3 × 50 = ₹150

⇒ Total Mixture = 3 + 1 = 4 units

⇒ Selling Price (SP) = 4 × 60 = ₹240

⇒ Profit = SP − CP = 240 − 150 = ₹90

⇒ Profit Percentage = (Profit ÷ CP) × 100

⇒ Profit Percentage = (90 ÷ 150) × 100 = 60%

∴ The correct answer is 60%.

Additional Information

Mixture Alligation

When two ingredients are mixed, the ratio is found using (Cheaper Price − Mean Price) : (Mean Price − Dearer Price).

Profit on Free Items

Adding water (costing ₹0) to milk increases the volume, thus the profit % = [(SP − CP)/CP × 100] + [Volume increase %].

Effective Profit %

Total Profit % = [(1 + % increase in price) × (1 + % increase in quantity) − 1] × 100.

Question 65

  1. AOption (a)

    7 : 2

  2. BOption (b)

    5 : 3

  3. COption (c)

    3 : 5

  4. DOption (d)

    2 : 7

View answer & explanation

Correct answer

Answer: (c)C.

3 : 5

Why this answer is correct

Given:

Speed at the time of going from A to B = 9 km/h

Speed at the time of going from B to A = 15 km/h

Concept used:

Time = Distance/Speed

Calculation:

Let the distance of A to B be x km

Ratio of Time  from B to A and from A to B = x15x9\rm\frac{\frac{x}{15}}{\frac{x}{9}}

⇒ x15×9x{\frac{x}{15}}\times{\frac{9}{x}}

⇒ 915{\frac{9}{15}}

⇒ 35{\frac{3}{5}}

So, ratio = 3 : 5

∴ Required ratio is 3 : 5.

Question 66

  1. AOption (a)

    105

  2. BOption (b)

    115

  3. COption (c)

    125

  4. DOption (d)

    95

View answer & explanation

Correct answer

Answer: (a)A.

105

Why this answer is correct

Given:

The sum of three positive numbers is 339

Ratio of 1st number and 2nd number = 3 : 7

Ratio of 2nd number and 3rd number = 5 : 9

Calculation:

1st number : 2nd number = 3 : 7     ----(i)

2nd number : 3rd number = 5 : 9      ----(ii)

By equaling 2nd number in both the equation we get,

1st number : 2nd number : 3rd number = 15 : 35 : 63

Let the numbers be 15x, 35x and 63x

Now,

According to the question,

15x + 35x + 63x = 339

⇒ 113x = 339

⇒ x = 339/113

⇒ x = 3

So, 2nd number = 35 × 3 = 105

∴ The second number is 105.

Question 67

What is the largest 4-digit number that is divisible by 10, 15 and 18?

  1. AOption (a)

    9900

  2. BOption (b)

    9090

  3. COption (c)

    9990

  4. DOption (d)

    9999

View answer & explanation

Correct answer

Answer: (c)C.

9990

Why this answer is correct

Given:

The number are 10, 15, and 18

Concept used:

We know that, If the number is divisible by given numbers then it should be the multiple of their LCM

Calculation:

LCM of 10, 15, and 18 = 90 

Now the largest 4-digit number is 9999

If we divide 9999 by 90 we get the remainder as 9

The number completely divisible by 10, 15, and 18 = 9999 - 9 

⇒ 9990 

∴ The largest 4-digit number that is divisible by each of 10, 15, and 18 is 9990.

Question 68

  1. AOption (a)

    3 min

  2. BOption (b)

    18 min

  3. COption (c)

    6 min

  4. DOption (d)

    12 min

View answer & explanation

Correct answer

Answer: (c)C.

6 min

Why this answer is correct

Given:

1st AC can cool in 10 min

2nd AC can cool in 15 min

Concept used:

Total work = Time taken by the objects to do a work × efficiency of the objects

Calculation:

LCM of 10 and 15 = 30 i.e total work

Now,

Efficiency of the 1st AC = 30/10 = 3 units/min

Efficiency of the 2nd AC = 30/15 = 2 units/min

Effective efficiency of the two ACs = 3 + 2 = 5 units/min

Time taken to cool the hall when two ACs are on together = 30/5

⇒ 6 min

∴ They will cool the hall in 6 min.

Question 69

  2. BOption (b)

    613%\frac{61}{3}\%%

  3. COption (c)

    1003\frac{100}{3}%

  4. DOption (d)

    413\frac{41}{3}%

View answer & explanation

Correct answer

Answer: (c)C.

1003\frac{100}{3}%

Why this answer is correct

Given:

The selling price of a toy is 43\frac{4}{3} of its Cost Price

Concept used:

Selling price = Cost price + profit

Profit% = [(Profit)/Cost price] × 100

Calculation:

Let the cost price of the toy be 3x

So, the selling price of the toy = 3x × 43\frac{4}{3}

⇒ 4x

Profit = 4x - 3x = x

Profit % = (x/3x) × 100

⇒ 100/3

∴ The profit percentage is 1003\frac{100}{3}%.

Question 70

Anil took some loan on simple interest at a certain rate and paid ₹12,800 as interest after 2 years. His friend Sumit also borrowed the same sum on compound interest for the same period and same rate of interest compounded annually and paid ₹704 more interest than that paid by Anil. What is the rate of interest per annum?

  1. AOption (a)

    10%

  2. BOption (b)

    11%

  3. COption (c)

    10.5%

  4. DOption (d)

    12%

View answer & explanation

Correct answer

Answer: (b)B.

11%

Why this answer is correct

Given:

S.I = Rs. 12800

Time = 2 years

Difference of C.I and S.I = Rs. 704

Concept used:

Difference between compound interest and simple interest for 2 years:

Difference = P × (R/100)2

S.I = (P × T × R)/100

Here, P = principal or sum, T = time, R = rate of interest

Calculation:

Let the sum be P and the rate be R

Now,

704 = P × (R/100)2

⇒ 704 = PR2/10000

⇒ (7040000/R2) = P

Again,

12800=(7040000R2×2×R)10012800 =\rm\frac{\left(\frac{7040000}{R^2} ×2 × R \right)}{100}

⇒ 12800=(7040000R×2)10012800 =\rm\frac{\left(\frac{7040000}{R} ×2 \right)}{100}

⇒ 12800=(7040000×2)100R12800 =\rm\frac{\left({7040000} ×2 \right)}{100R}

⇒ R=(7040000×2)100×12800\rm R =\rm\frac{\left({7040000} ×2 \right)}{100 ×12800}

⇒ R = 11

So, rate = 11%

∴ The rate of interest per annum is 11%.

  2. BOption (b)

    ₹2,432

  3. COption (c)

    ₹2,500

  4. DOption (d)

    ₹2,439

View answer & explanation

Correct answer

Answer: (b)B.

₹2,432

Why this answer is correct

Given:

Actual price of the oven = Rs. 3200

Discount% = 20% and 5%

Concept used:

Selling price = Actual price × (100 - discount%)/100

Calculation:

Price after 1st discount = 3200 × 80%

⇒ Rs. 2560

Price after 2nd discount = 2560 × 95%

⇒ Rs. 2432

So, she paid = Rs. 2432

∴ She paid Rs. 2432.

Question 72

A fruit seller had some oranges. He sold 30% oranges and still had 210 oranges. The number of oranges he had, initially, was:

  1. AOption (a)

    300

  2. BOption (b)

    200

  3. COption (c)

    150

  4. DOption (d)

    350

View answer & explanation

Correct answer

Answer: (a)A.

300

Why this answer is correct

Given:

The seller sold 30% of the oranges what he had

Remaining oranges = 210

Calculation:

Let the seller have 100a oranges

According to the question,

100a - 100a × 30% = 210

⇒ 70a = 210

⇒ a = 210/70

⇒ a = 3

So, total number of oranges = 100 × 3

⇒ 300

∴ The number of oranges he had, initially, was 300.

Question 73

At what rate of simple interest will a sum of ₹4,500 amount to ₹5,310 after 4 years?

  1. AOption (a)

    4.5%

  2. BOption (b)

    4.0%

  3. COption (c)

    3.5%

  4. DOption (d)

    5.5%

View answer & explanation

Correct answer

Answer: (a)A.

4.5%

Why this answer is correct

Shortcut Trick

Total Simple Interest for 4 years = ₹5,310 − ₹4,500 = ₹810

Simple Interest for 1 year = 810 ÷ 4 = ₹202.5

Rate % = (1-year Interest ÷ Principal) × 100

Rate % = (202.5 ÷ 4500) × 100 = 4.5%

∴ The correct answer is 4.5%.

Alternate Method

Given:

Principal (P) = ₹4,500

Amount (A) = ₹5,310

Time (T) = 4 years

Formula Used:

Simple Interest (SI) = (P × R × T) ÷ 100

Amount (A) = P + SI

Calculations:

⇒ SI = A − P

⇒ SI = 5310 − 4500 = ₹810

⇒ 810 = (4500 × R × 4) ÷ 100

⇒ 810 = 45 × R × 4

⇒ 810 = 180 × R

⇒ R = 810 ÷ 180

⇒ R = 4.5%

∴ The correct answer is 4.5%.

Additional Information

Compound Interest

When interest is compounded annually, Amount A = P × (1 + R÷100)T.

SI vs CI Difference

For 2 years, the difference between Compound Interest and Simple Interest on the same principal is P × (R÷100)2.

Rule of 72

A simple rule to estimate the number of years required to double the invested money at a given annual interest rate (Time ≈ 72 ÷ R).

Question 74

    20.5

  2. BOption (b)

    26

  3. COption (c)

    7.1

  4. DOption (d)

    11

View answer & explanation

Correct answer

Answer: (c)C.

7.1

Why this answer is correct

Given:

A trader marked up his articles 25% more than the cost price.

He offered a discount of 10%

Concept used:

Selling price = Marked price × (100 – discount)%

Profit% = [(Selling price - Cost price)/Cost price] × 100

Calculation:

Let the cost price be 100a.

Marked price = 100a × 126%

⇒ 126a

Selling price = 126a × 85%

⇒ 107.1a

Profit% = [(107.1 - 100)/100] × 100

⇒  7.1%

∴ Trader’s gain percentage is 7.1

Shortcut Trick

CP/MP = (100 - D%)/(100 + P%)

100/126 = (100 - 15)/(100 + P%)

100/126 = 85/(100 + P%)

(100 + P%) = 85 × 126/100

(100 + P%) = 17 × 63/10

(100 + P%) = 107.1 

P% = 7.1% 

Hence, the correct answer is 7.1%
