Thus, Vani is tall from red house and She is wearing a frocks means that Vani is not wearing a Sarees.

Hence, ‘Vani’ is the correct answer.

Here the logic is:

Total numbers of alphabets in word ⨯ 2

SCIENCE = 7 (Total numbers of alphabets) ⨯ 2 = 14

MATHS = 5 (Total numbers of alphabets) ⨯ 2 = 10

Similarly,

EXAMINATION = 11 (Total numbers of alphabets) ⨯ 2 = 22

Hence, ‘22’ is the correct answer.

When mirror is placed at the right side of the word we get -

Hence, ‘option 1’ is the correct answer.

Square of place value of alphabets comes in the answer -

K → 11 → 11² → 121

N → 14 → 14² → 196

Similarly,

R → 18 → 18² → 324

U → 21 → 21² → 441

Hence, ‘324 441’ is the correct answer.

1. Given expression : 8 ÷ 2 + 4 = 10

Interchanged the sign and number ÷ and +, 8 and 4 -

3. Given expression : 8 ÷ 2 + 4 = 10

Interchanged the sign and number + and ÷, 8 and 2

LHS = 2 + 8 ÷ 4

= 2 + 2

= 4 ≠ R.H.S

4. Given expression : 8 ÷ 2 + 4 = 10

Interchanged the sign and number + and ÷, 2 and 4

LHS = 8 + 4 ÷ 2

= 8 + 2

= 10 = RHS

Hence, ‘ + and ÷, 2 and 4’ is the correct answer.

Concept:

• Meaning of "Some A are B" in Syllogism - there is at least one point in A which is in B.
• Meaning of "All A are B" in Syllogism - each point of A is in B.
• This explains why "some" can be considered as a subset of "all".
• Therefore, if "All A are B" is true, then "some A are B" is always true.

The least possible Venn diagram for the given statements is as follows -

Conclusions:

I. Some girls are not brown → True (It is definitely true because some girls are woman and no woman is brown  since which part of girls that is women can never be brown, hence true)

II. Some women are girls → True (It is definitely true because some girls are woman so some women are girls)

Hence, Both conclusions I and II follow.

The pattern will appear when the transparent sheet is folded at the dotted line -

Hence, ‘option 2’ is the correct answer.

Let us consider all of them facing inside.

1. Guna, who is second to the left of David, is the neighbour of Sekar and Raja.

2. David is not the neighbour of Hari and Raja. (So raja is immediate left of Guna)

3. Ajith is the neighbour of Bala and Hari. (So, Hari is immediate right of Ajith)

Hence, ‘Third to the left of Sekar’ is the correct answer.

Here the logic is:

1. For first step - (Given Number + 1) (Multiply by 1)
2. For second step - (Given Number + 1) ( Multiply by 2)
3. Similarly we will add 1 in all steps and multiplication factor increased by 1 in each step. (As 1,2,3,4....)

Here 445 is correct in place of 446.

Hence, ‘446’ is not belong to that group.

Given:

Length of hall = 15 m

Breadth of hall = 12 m

Sum of areas of floor and ceiling = Sum of areas of 4 walls

Formula used:

Sum of area of floor = Sum of area of ceiling = Length × Breadth

Sum of areas of 4 walls = 2 × height (length + breadth)

Volume of hall = length × breadth × height

Calculation:

Sum of area of floor = sum of area of ceiling = (15 × 12) m²

⇒ 180 m²

Total area of floor and ceiling = (180 + 180) m²

⇒ 360 m²

Sum of areas of 4 walls = 2H(15 + 12)

⇒ 54H

Now, according to question,

54H = 360 m²

⇒ H = 20/3 m

Volume of hall = 15 × 12 × (20/3) m³

⇒ 1200 m³

∴ The volume of hall is 1200 m³

Shortcut Trick

Sum of ages of Captain (28) and Wicketkeeper (32) = 60 years.

Excluding them reduces the average of 9 players by 2 years.

Total age shifted from 9 players = 9 × 2 = 18 years.

Average age of team × 2 = 60 − 18 = 42 years.

Average age = 42 ÷ 2 = 21 years.

∴ The correct answer is 21 years.

Alternate Method

Given:

Number of team members = 11

Age of Captain = 28 years

Age of Wicketkeeper = 28 + 4 = 32 years

Formula Used:

Average = Sum of observations ÷ Number of observations

Calculations:

Let the average age of the whole team be x years.

⇒ Total age of 11 players = 11x

⇒ Sum of ages of Captain and Wicketkeeper = 28 + 32 = 60 years

⇒ Total age of remaining 9 players = 11x − 60

⇒ Average of remaining players = (11x − 60) ÷ 9

⇒ According to the question: (11x − 60) ÷ 9 = x − 2

⇒ 11x − 60 = 9(x − 2)

⇒ 11x − 60 = 9x − 18

⇒ 11x − 9x = 60 − 18

⇒ 2x = 42

⇒ x = 21 years

∴ The correct answer is 21 years.

Additional Information

Sum of Observations

The total sum can always be calculated as: Sum = Average × Number of items.

Effect of Excluding Values

When values higher than the average are removed, the new average decreases. When values lower than the average are removed, the new average increases.

Weighted Average

For two groups with averages A₁ and A₂ and sizes n₁ and n₂, the combined average is (n₁A₁ + n₂A₂) ÷ (n₁ + n₂).

Given:

First number = 25% more than third number

Second number = 50% more than third number 

Calculations:

Let the third number be 100

First number = 100 + 25% of 100

First number = (25/100) × 100 + 100

⇒ 25 + 100 = 125

Second number = 100 + 50% of 100

Second number = (50/100) × 100 + 100

⇒ 50 + 100 = 150

The ratio of first to the second number = 125 ∶ 150 ⇒ 5 ∶ 6

∴ The ratio of the first number to the second number is 5 ∶ 6

Given:

Original speed = 10 km/hr

Imaginary speed = 15 km/hr

Formula used:

Distance = Speed × Time

Calculation:

Let the time taken be T

According to question,

15T – 10T = 25

⇒ 5T = 25

⇒ T = 5 hours

Original distance travelled = (10 × 5) km

⇒ 50 km

∴ The actual distance travelled by him was 50 km

Calculation:

Total numbers of number from 1 to 80 = 80

Numbers which have 1 or 9 in the unit digit = 1, 9, 11, 19, 21, 29, 31, 39, 41, 49, 51, 59, 61, 69, 71, 79

Number of numbers which have 1 or 9 in the unit digit = 16

Required percentage = (16/80) × 100%

⇒ 20%

∴ The required percentage is 20%

Given:

Discount = 35%

If, there was no discount, Raj would have paid Rs. 238 more

Formula

SP = MP(1 - D/100)

SP = Selling price

MP = Marked price

D = Discount

Calculation:

Let the M.P be 100x

S.P after 35% discount = 100x × (65/100)

⇒ 65x

Now, According to question,

⇒ 35x = Rs. 238

⇒ 65x = Rs. 238 × (65x/35x)

⇒ Rs. 34 × 13

⇒ Rs. 442

∴ Raj paid Rs. 442 for the chair

Alternate MethodAccording to the question,

35x/100 = 238

⇒ x = 23800/35

⇒ x = 680 

Raj pay for the chair = 680 - 238

⇒ Rs 442 

∴ Raj paid Rs. 442 for the chair

Given:

Profit = 340% of the cost

Increase in cost = 32%

Formula used:

Profit % on the cost price = (Profit/Cost price) × 100

Profit % on the selling price = (Profit/Selling price) × 100

Profit = Selling price – Cost price

Calculations:

Let the cost price be Rs. 100 and the selling price be SP

⇒ Profit = (SP – CP) 

Profit = 340 % of CP = Rs. 340

⇒ 340 = SP - 100

⇒ SP = Rs. 440

After increase in cost price

New cost price = 100 + (32/100) × 100 ⇒ Rs. 132

New profit = 440 – 132 ⇒ Rs. 308

Profit on the selling price = (308/440) × 100

⇒ 770/11 = 70%

∴ The new profit is 70% of the selling price

Calculation:

According to question,

20% = Rs. 30,600

⇒ 25% = Rs. (30,600/20%) × 25%

⇒ Rs. 1530 × 25

⇒ Rs. 38,250

∴ The amount to be paid as paper cost is Rs. 38,250

Given :

Let the total number be = 5 

Mean of the numbers = 9 

Calculations :

Total sum of the numbers = mean × total numbers 

⇒ 9 × 5 

⇒ 45 

So, x + x + 4 + x + 5 + x + 7 + x + 9 = 45 

⇒ 5x + 25 = 45 

⇒ x = 4 

Now the mean of the last three numbers = sum of the last three numbers/3 

sum of last three numbers = x + 5 + x + 7 + x + 9 = 33 

Mean = 33/3

⇒ 11 

∴ Average of last 3 numbers is 11

Concept Used: 

Greatest divisor = HCF[(a - b), (b - c), (a - c)]; where a > b > c

Calculation:

⇒ greatest number = HCF[(187 - 47), (95 - 47), (187 - 95)]

⇒ greatest number = HCF[140, 48, 92] = 4

∴ Required greatest number that will divide 47, 95 and 187 so as to leave the same remainder in each case = 4

Given :

Binding section consist 20% of total distribution 

Calculations : 

Total angle distribution = 360° 

Total percentage distribution = 100%

100% = 360° 

1% = 3.6° 

20% = 20 × 3.6° 

⇒ 72° 

∴ Total angle distribution for binding is 72°

Given :

Principle = Rs 40000 

Rate of interest = 6% 

Total interest = Rs 4944 

Formula used :

P[(1 + (r/100)]ⁿ = amount (where P = principle, r = rate of interest and n = number of years)

Calculations :

Total amount = Principle + interest = 40000 + 4944

⇒ 44944 

Now according to the question

40000[(1 + (6/100)]ⁿ = 44944

(106/100)ⁿ = 44944/40000

(53/50)ⁿ = 2809/2500

n = 2 

∴ Period of time is 2 years

Concept used:

Follow BODMAS rule to solve this question, as per the order given below

Calculation:

Considering the given equation

⇒ 4²/5 + 5 × 2 - 3 of 4 = ?

⇒ 16/5 + 5 × 2 - 12 = ?

⇒ 16/5 + 10 - 12 = ?

⇒ ? = 6/5 = 1.2

Given:

Radius of circle = 8 cm

Base of triangle = 8 cm

Area of circle = Area of triangle

Formula used:

Area of circle = π R²

Area of triangle = (1/2) × Base × Altitude

Calculations:

Area of circle = Area of triangle

⇒ π × 8 × 8 = (1/2) × 8 × Altitude

⇒ Altitude = 2 × 8 × π

⇒ Altitude = 16 π

∴ The Altitude of the triangle is 16 π cm

Given :

Speed of train is 50% faster than car 

Distance between point A and B = 60 km

Time taken by train is  to cover 60 km = (t - 12.5) minutes or (t - 12.5)/60 hours

Time taken by car to cover 60 km = t minutes or t/60 hours 

Formula Used :

Speed = Distance/time 

Calculations :

Let the speed of car be S

Speed of train is 50% more than car = S + 50% of S = (3/2)S

Now for train 

⇒ 60 = (3/2)S × (t - 12.5)/60      ...(1)

Now for car  

⇒ 60 = S × (t/60)      ...(2)

Solving both equations

value of t = (75/2) minutes or (5/8) hours 

Speed of car = distance/Speed 

⇒ 60/(5/8)

⇒ 96 km/hours 

∴ The speed of the car is 96 km/hour 

Alternate Method Here, 50% = 1/2. So, Ratio of speed of train to car = 3 : 2 ⇒ 3x and 2x respectively

Now, Let the time taken by car = t hours,

Then the time taken by train = t -12.5min = t - 12.5/60 h

⇒ (t -5/24)h

Since distances are equal 

⇒ 3x × ( t - 5/24) = 2x × t

⇒ 3t - 5/8 = 2t

⇒ t = 5/8 h

Now, speed of car = Distance/Time = 60 ÷ 5/8

⇒ 60 × 8/5 = 96km/h

Given :

 A person when sells his laptop at 4500 rupees he will lose of 10% 

Formula

selling price = cost price - loss% of cost price 

Calculations :

Selling price of laptop = 4500 

Loss percent = 10% 

⇒ 4500 = cost price - 10% of cost price 

⇒ 4500 = 90% of cost price 

cost price = 5000 rupees 

Now according to question he need 20% profit 

so new selling price = cost price + 20% of cost price 

⇒ 5000 + 20% of 5000 ⇒ 5000 + 1000 

⇒ 6000 rupees 

∴ He will sell at 6000 rupees to gain 20% on cost price   

SP = 4500 

Loss = 10%

CP = 4500 × 100/90

CP = 5000

new SP after 20% profit = 5000 × 120/100

SP = 6000

Given:

Earning of 15 workers in 10 days = Rs. 1800

Concept used:

Earning is directly proportional to the product of the number of workers and time taken

Calculation:

According to question,

15 × 10 = Rs. 1800

Then, 5 × 8 = Rs. 1800 × [(5 × 8)/(15 × 10)]

⇒ Rs. 1800 × (40/150)

⇒ Rs. 480

∴ The earning of 5 workers in 8 days is Rs. 480

Given :

Height of the pipe = 28 cm 

External Radius = (external Diameter/2) = 5 cm 

Thickness of Pipe = 2 cm 

Formula :

Volume of the pipe = π (R² - r²)h ( where R = external radius, r = internal radius and h = height of the cylinder)

Calculations :

Internal radius = external radius - thickness 

⇒ r = 5 - 2 = 3 cm

Volume of Cylinder = π (R² - r²) h 

⇒ π (5² - 3²) × 28 

⇒ 1408 cm³

Weight = volume × density 

⇒ 1408 × 5 

⇒ 7040 gms 

∴ Weight of cylinder is 7040 gms

Given :

Ratio of Ravi and Sumit salaries is 2 : 3 

Their new ratio becomes 35 : 50 after salary of each is increased by ₹3000 

Calculations :

Let the salary of Ravi = 2x 

Let the salary of Sumit = 3x 

Now according to the question 

(salary of Ravi + 3000) : (Salary of Sumit + 3000) = 35 : 50

(2x + 3000) : (3x + 3000) = 7 : 10

⇒ x = 9000 rupees 

Sumit' salary = 3x = 27000

Sumit's new salary = 27000 + 3000 = 30000 rupees 

∴ Sumit's new salary will be Rs 30000

Given :

Family has two grand parents, three parents and four children 

Average age of grand parents is 65 years

Average age of parents is 32 years 

Average age of grand children is 8 years

Calculations :

Total age of two grand parents = 65 × 2 = 130 years

Total age of three parents = 32 × 3 = 96 years 

Total age of grand children = 8 × 4  = 32 years 

Total family members = 2 + 3 + 4 = 9 

Total age of family members = 130 + 96 + 32 = 258 years 

Average age of the family = (total age/total number of persons) 

⇒ 258/9 

⇒ 28(2/3)

∴ The average age of family members = 28(2/3) years

Given :

Royalty on books = 15% 

Paper cost = 25%

Calculations :

Let the number of total cost be 100 rupees 

Royalty on books = 15% of 100 = 15 rupees 

Paper cost = 25% of 100 = 25 rupees

Percentage of Royalty on books less than paper cost = (Paper cost - Royalty oon books)/Paper cost × 100 

⇒ (25 - 15)/25 × 100 

⇒ 40% 

∴ Royalty on books is 40% less than paper cost

Given:

Interest paid after 9 years = Rs. 13,300

Rate of interest for first 2 years = 6%

Rate of interest for last 4 years = 14%

Formula used:

S.I = PRT/100

Calculation:

Interest for first 2 years = (P × 6 × 2)/100

⇒ 3P/25

Interest for next 3 years = (P × 9 × 3)/100

⇒ 27P/100

Interest for last 4 years = (P × 14 × 4)/100

⇒ 14P/25

Now, as per the question,

(3P/25) + (27P/100) + (14P/25) = Rs. 13,300

⇒ 95P/100 = Rs. 13,300

⇒ 19P/20 = Rs. 13,300

⇒ P/20 = Rs. 7000

⇒ P = Rs. 14,000

∴ The amount he borrowed was Rs. 14,000

Concept used:

Given:

A can complete the work in = 20 days

B can complete the work in = 40 days

C can complete the work in = 80 days

Calculations:

A’s 1 day work = 1/20

B’s 1 day work = 1/40

C’s 1 day work = 1/80

(A + B + C)’s 1 day work = (1/20) + (1/40) + (1/80)

⇒ (4/80) + (2/80) + (1/80) = 7/80

A works for first two days and then assisted by B and C on the third day

A’s 2 day work = (1/20) × 2 = 1/10

Then the work done in 3 days = (1/10) + (7/80) ⇒ 15/80

The work done in 3 days =15/80 ⇒ 3/16

Work done in 15 days = 15/16

Remaining work = 1 – 15/16 ⇒ 1/16

On 16^th and 17^th day A will work alone

If A can do (1/20) work in 1 day then it will finish (1/16) work in (20/16) days

The total work will be completed in

⇒ 15 + (20/16) = 65/4 days

⇒ 65/4 days = 16.25 days

∴ Total work will be completed in 16.25 days or 16 days (from the options)

 

Concept Used:

Total work = Time taken (Number of Days) × Efficiency

Calculation:

Total work = 80

A’s efficiency = 4

B’s efficiency = 2

C’s efficiency = 1

A works for first 2 days and then assisted by B and C on the third day

Work done in 3 days = 4 × 2 + (4 + 2 + 1)

⇒ 8 + 7 = 15

Work done in 15 days = 15 × 5 ⇒ 75

Remaining work = 80 – 75 = 5

For the next two days A alone will work

Then the remaining work will be completed by A in = 5/4 days

∴ Total work will be completed in 16.25 days or 16 days (from the options)

⇒ 1/16

Given:
