= 615

Hence, '615' is the correct answer.

The faces opposite to each other is shown below:

 

 → When 6 is on the top position and 5 is on the front side, 4 must be on Left Side, but in image A, it is on the right of 5, which is incorrect.

 

 

→ Can be formed.

 → Can be formed.

 → Cannot be formed as 6 and 3 are opposite faces.

Hence, 'Both B and C' is the correct answer.

The logic followed here is:

Logic: In a row: (Third number - First Number) ÷ 3 = Second Number

Row 1: (73 - 49) ÷ 3 = 24 ÷ 3 = 8

Row 2: (29 - 11) ÷ 3 = 18 ÷ 3 = 6

Similarly,

Row 3: (58 - ?) ÷ 3 = 12

⇒ 58 - ? = 12 × 3

⇒ 58 - ? = 36

⇒ 58 - 36 = ?

⇒ 22 = ? 

Hence, '22' is the correct answer.

The logic followed here is:

Similarly,

Hence, 'RAKM' is the correct answer.

Given:

The sum of the length, breadth and height of a cuboid is 18 cm.

The length of its diagonal is 13 cm,

Formula used:

If the length, breadth, and height of a box are l, b, and h respectively

Then, the diagonal of the of the cuboid = √(l2 + b2 + h2)

The total surface area of the cuboid is = 2(lb + bh + bl)

Calculation:

As per the question,

Diagonal of the of the cuboid = 13

⇒ √(l2 + b2 + h2) = 13

⇒ (l2 + b2 + h2) = 169

Now,

(l + b + h) = 18

(l + b + h)² = 18²

⇒ (l2 + b2 + h2) + 2 (lb +bh+bl) = 324

⇒  2 (lb +bh+bl) = 324 - 169

⇒ 155 cm²

∴ The total surface area of the cuboid is 155 cm²

Given:

Ram bought an article for ₹6,800 and spent ₹700 on its repairs.

He marked his article at 8% above the overall cost price.

He sold the article for ₹6,196.50 after giving two successive discounts of 10% and x%

Concept used:

Total cost price = Article's cost price + spent on its repair

Calculation:

Total cost price = 6800 + 700

⇒ Rs 7500

So the market price = 7500 × (108 / 100)

⇒ Rs 8100

After 1st discount,

selling price = 8100 - 8100 × 10/100

⇒ 8100 - 810

⇒ Rs 7290

So 2nd discount amount = 7290 - 6,196.50

⇒ 1093.50

So 2nd  discount percentage (x)  = (1093.50 / 7290) × 100

⇒ 15%

∴ The value of x is 15%

Additional Information 

Profit is calculated on Cost Price.

And discount is calculated on Market Price.

Given:

A sum of Rs8,400 is divided between A and B such that A's share at the end of 2 years is equal to B's share at the end of  (2)years 8 months

At 15% p.a., interest compounded for 8 months.

Concept used:

Amount = Principal(1 + Rate of interest /100)

Calculation:

Interest rate for 8 monthly = (15 /12) × 8

⇒ 10%

Let one part A be x, so other part b = 8400 - x

As per the question,

x (1 + 10/100)³  = (8400 - x) (1 + 10/100)⁴ 

⇒ x = (8400 - x) × 11/10

⇒ x = 400 × 11

⇒x = Rs 4400

A's share  in the given sum is Rs 4400

Given:

Pipes A and B can fill a tank in 12 h and 18 h, respectively,

whereas pipe C can empty the full tank in 8 h.

A and B opened for $4\frac{1}{2}$ h and then closed.

Concept used:

Efficiency = (Total work / Total time taken)

Efficiency = work done in a single day 

Calculation:

Let total work is 72 units ( LCM of 12, 18 and 8)

The efficiency of A = 72 /12 = 6 units

The efficiency of B = 72 / 18 = 4 units

So A + B together do in one day 6 + 4 = 10 units

So they do in 4.5 hours, 4.5 × 10 = 45 units

c empty 45 units alone

So, the efficiency of C = 72 / 8 =  9 unit

So, C takes 45 / 9= 5 hours to empty the tank

∴ C alone will empty the tank in 5 hr.

Given:

Two numbers are in the ratio 2 : 3.

The product of their LCM and HCF is 7350. 

Formula used:

LCM × HCF = Multiplication of the numbers 

Calculation:

Let one number be 2x.

so,other number be 3x

So as per the formula,

(2x) × (3x) = 7350

⇒ 6x² = 7350

⇒ x² =  1225

⇒ x = 35

The difference is 3x - 2x = x

∴ The difference is 35

Given:

A sold an article to B at 24% profit.

B sold it to C at 30% profit.

B's profit was Rs 72.60 more than that of A

Concept used:

SP = CP + profit

Profit is calculated on cost price

Calculation:

Let the CP of A = 100

SP of A =124

SP of B = 124 + 124 × 30/100

⇒ 124 + 37.20 = 161.20

B's profit = 161.20 - 124

⇒37.2

The difference in profits, 37.20 - 24 =13.20

As per the question,

Value of 13.2 units = 72.60

Value of 124 units = (72.60 / 13.2) × 124

⇒ 5.5 × 124 = Rs 682

∴ B paid for it Rs 682

Shortcut Trick

LCM + HCF = 148

LCM − HCF = 140

⇒ LCM = (148 + 140) ÷ 2 = 144

⇒ HCF = (148 − 140) ÷ 2 = 4

⇒ Other Number = (LCM × HCF) ÷ Given Number = (144 × 4) ÷ 16 = 36

∴ The correct answer is 36.

Alternate Method

Given:

Sum (L + H) = 148

Difference (L − H) = 140

One number (a) = 16

Formula Used:

Product of two numbers = LCM × HCF

Calculations:

Adding the two equations:

⇒ (L + H) + (L − H) = 148 + 140

⇒ 2L = 288

⇒ L (LCM) = 144

Subtracting the equations:

⇒ (L + H) − (L − H) = 148 − 140

⇒ 2H = 8

⇒ H (HCF) = 4

Let the other number be b:

⇒ 16 × b = 144 × 4

⇒ b = 576 ÷ 16

⇒ b = 36

∴ The correct answer is 36.

Additional Information

HCF and LCM Relation

For any two numbers a and b, a × b = HCF(a, b) × LCM(a, b). This property is only valid for two numbers.

HCF Property

The HCF of two or more numbers is always a factor of their LCM.

Co-prime Numbers

If two numbers are co-prime, their HCF is 1 and their LCM is equal to the product of the numbers.

Given:

The income of A and B are in the ratio 8 : 11,

And the ratio of their savings is 7 : 9.

The expenditure of A and B is Rs25,000 and Rs35,000, respectively.

Concept used:

Income - savings = Expenditure 

Calculation:

Let the income of A and B be 8x and 11x respectively.

And the savings of A and B are 7y and 9y respectively.

As per the question,

8x - 7y = 25000 ....... (1)

11x - 9y= 35000....(2)

By solving both equations we get,

x = 4000 and y = 1000

Income of B = 11 × 4000 =  Rs 44000

∴ The income of B is Rs 44000

Given:

When the speed of a car is increased by 25%, it takes 24 minutes less to cover the same distance. 

Formula:

 Distance = Speed × Time

Concept used:

The speed ratio is inversely proportional to the time ratio.

Calculation:

Let, the speed of the car be 100 units

So after increased speed = (100 + 100 × 25/100) 

⇒ 100 + 25 = 125 units

So speed ratio is 100: 125 = 4: 5

So, the time ratio will be 5:4

Let, the time at 1st be 5x and then be 4x

As per the question 5x - 4x = 24 

⇒ x = 24 minutes 

So, initial time 

5x = 5 × 24

⇒ 120 minutes = 2hr

∴ The time  taken to cover the same distance at the actual speed is 2 hour

Given:

A and B can complete a work in 12 days and 18 days, respectively.

They worked together for 4 days after which B was replaced by C

And the remaining work was completed by A and C in the next 4 days.

Concept used:

Efficiency = (Total work / Total time taken)

Efficiency = work done in a single day 

Calculation:

Let total work be 36 units ( LCM of 12 and 18)

The efficiency of A = 36 /12 =  3 units

The efficiency of B = 36 / 18 =  2 units

So A + B together do in one day 3 + 2 = 5 units

So they do in 4 days 5 × 4 = 20 units

Remaining 36 - 20 = 16 units done by A + C in 4 days 

The efficiency of A + C = 4 units

So the efficiency of C = 4 - 3 =  1unit

So, C takes 36 / 1 = 36 days to do the total work

C, 36 / 3 = 12 days to do the one-third total work

∴ C alone completed one-third of the same work in 12 days

Additional Information (The efficiency of a Person is inversely proportional to the number of days to complete the work)

Given:

Sushma has invested 40% more than Reshma,

Reshma has invested 30% less than Divya.

The amount invested by Divya is Rs 6,000

Calculation:

Reshma has invested = 6000 × 70 /100

⇒ Rs 4200

Sushma has invested = 4200 × 140 /100

⇒ Rs 5880

∴The amount invested by Sushma is Rs 5880

Given:

The cost prices of the two articles are in the ratio 4 : 5.

Selling the first article at 10% profit and the second at 20% profit 

The difference of Rs 480 in their selling prices.

Concept used:

Selling Price = CP + (Profit percentage / 100) × CP

Calculation:

Let, the cost price be 4x and 5x

The selling price of the 1st article is

4x + 4x × (10/100)

⇒ 4x + 0.4x

⇒ 4.4x

The selling price of the 2nd article is

5x + 5x × (20/100)

⇒ 5x + x

⇒ 6x

As per the question,

6x - 4.4x = 480

⇒ 1.6x = 480

⇒ x = 480 / 1.6

⇒ x = 300

So the total cost price of two article = 4x + 5x =  9x

Value of 9x = 9 × 300 = Rs 2700

∴ The cost price is Rs 2700

Shortcut Trick Among the given options, 2700 is only divisible by 9.

And from the question, it is clear that the option will be a multiple of 9 = (4 + 5) always

So, the answer will be Rs 2700

Given:

A trader earns a profit of 20% by selling an article after giving a discount of 20% on the marked price of the article.  

The cost price of the article is Rs 448

Formula used:

If a shopkeeper wants a profit of R% after allowing a discount of r%

Then the Market price(MP) of the item = CP × ($\frac{100+R}{100-r}$)

Calculation:

As per the question,

448 = MP × (100 - 20) / (100 + 20)

⇒ 448 = MP × (80/120)

⇒ 448 = MP × (80/120)

⇒ MP = (448 × 120) / 80

⇒ Rs 672

∴  the market price of the article is Rs 672

Additional Information 

Profit is calculated on Cost Price.

And discount is calculated on Market Price

Concept used:

BODMAS rule.

Calculation:

36 ÷ 18 of 3 × 2 + 8 ÷ 4 of 2 × 5 - 5 ÷ 10 × 2

⇒ 36 × (1/18) × (1/3)  × 2 + 8  × 1 / 4  × 1 / 2  × 5 - (5 /10) × 2

⇒ (2/3)  × 2 + 5 - 1

⇒ 4 / 3 + 4

⇒ 16 / 3 =  $5\frac{1}{3}$

∴ The value is  $5\frac{1}{3}$

Given:

Sudha gains 30% by selling an article for Rs 91.

she sells it for Rs 78.75

Concept used:

Cost price = Selling price ×( $\frac{100}{100+Gain}$)

CP + Profit = SP

Calculation:

The cost price of the article = 91 × 100/130

⇒ 70

So profit by sells it for Rs 78.75 = 78.75 - 70

⇒ 8.75

Profit percentage = (8.75 / 70) × 100

⇒ 12.5%

∴  the profit percentage is  $12\frac{1}{2}\%$

Given:

A spherical ball of radius 3 cm, is immersed in water contained in a vertical cylinder of radius 5 cm.

Formula used:

Volume of sphere = (4/3)πr³

Concept used

Volume of sphere = Volume of cylinder

Calculation:

As per the question,

 π × (5)² ×  h = (4/3) × π × (3)³

⇒ h= (4/3) ×  27 /25

⇒ h= 36 /25

⇒ h= 1.44 cm

The rise in the water level is 1.44 cm.

Given:

The sum = Rs 30,051

In 3 years if the rate of interest is 5% for the 1st year, 6% for the 2nd year and 8% for the 3rd year

Concept used:

Compound interest = interest on interest + interest on principal

Calculation:

The option test will be the best way to solve these questions.

for 1st year interest will be 25000 × 1 × 5 / 100 = Rs1250

Total amount after 1st year is 25000 + 1250 = Rs 26250

for 2nd year amount will be,

26250 + (26250 × 1 × 6) / 100 

⇒ 26250 + 1575 =  Rs 27825

In 3rd year, 

The amount will be,

27825 + (27825  × 1 × 8) / 100 

⇒ 27825 + 2226 = Rs 30051

∴ So, the sum is Rs 25000

Given:

A train takes 1 hour and 12 minutes to cover a certain distance at a speed of 80 km/h

The speed is increased by 25%

Concept used:

Distance = speed × Time

Calculation:

1hr 12 min = 6 / 5 hr

Total distance = 80 × 6 / 5 =  96 km

25 / 3 of the distance = 96 × 25 / 3 = 800 km

Now changed speed = 80 × 125 / 100 = 100 km / hr

Time = 800 /100 = 8 hr

∴ The time will take to cover $\frac{{25}}{3}$ of the distance is 8hr

Given:

The pass percentage in an examination is 35% of the total marks.

A student scored 390 marks and was declared fail by 65 marks.

Calculation:

A student scored 390 marks and was declared fail by 65 marks

So the passing marks is 390 + 65 = 455

As per the question,

The pass per cent of these sections are 80%, 76%, 64%, 65% and 70%, respectively. 

Calculation:

Pass candidate Class X has 5 sections which have 40 students is 40 × 80 /100 = 32

Pass candidate Class X has 5 sections which have 50 students is 50 × 76 /100 = 38

Pass candidate Class X has 5 sections which have 50 students is 50 × 64 /100 = 32

Pass candidate Class X has 5 sections which have 60 students is 60 × 65 /100 = 39

Pass candidate Class X has 5 sections which have 60 students is 60 × 70 /100 = 42

Total number of candidates is 40 + 50 + 50 + 60 + 60 = 260

Total number of passing candidates is  32 + 38 + 32 + 39 + 42 = 183

Passing percentage (183 / 260) ×  100 = 70.38 %

The total Passing percentage is 70.38%

Given:

The boys and girls in a school are in the ratio 7 : 5.

60% of the boys and 40% of the girls are aged 14 years and below the age of 14 years 

The number of students above the age of 14 years is 870

Calculation:

Let, the number of boys be 70 units 

number of boys be 50 units 

Total number of students is 70 + 50 = 120 units 

So, the boys aged 14 years and below the age of 14 years = 70 × 60/100

⇒ 42 units 

the number of boys above the age of 14 years is = 70 - 42

⇒ 28 units 

So, the girls aged 14 years and below the age of 14 years = 50 × 40/100

⇒ 20 units 

the number of boys above the age of 14 years is = 50 - 20 = 30 units

Total students above the age of 14 years are = 30 + 28 =  58 units

As per the question,

Value of  58 units = 870

⇒ 120 units = (870 × 120) / 58 =1800

∴ The total number of students is 1800

Given:

The average weight of 5 persons increases by 2.8 kg

A new person comes in place of one of them weighing 38 kg

Calculation:

So the weight of the new person = 38 + 14 = 52 kg

The weight of the new person is 52 kg

Alternate Method

Formula used:

If the average weight of b person increases by n kg when a new person comes in place of one of them weighing a kg

Then the weight of the new member = a + nb

Calculation,

So the weight of  the new person will be,

38 + 2.8 × 5 = 52 kg

The weight of the new person is 52 kg

Given:

The compound interest on ₹20,000 at 9% per annum for one year and 4 month.

Concept used:

Compound interest means the interest on interest and the interest on principal both.

Calculation:

So the interest rate for month = (9 / 12) × 4 =  3%

So the interest for 1 yr = (20000 × 1 × 9 )/ 100 = Rs 1800

Interest for last 4 month = (1800 × 1 × 3 + 20000 × 1 × 3) / 100

⇒ 500 + 154 =  654

Total interest for 1 yr and 4 months will be 1800 + 654 =  Rs 2454

∴The Interest is Rs 2454

Given:

Calculation:

The total number of 19 students is = (74 × 19) =  1406

By mistake, he wrote the number 65 instead of 56

So total increased value = 65 - 56 = 9

New, correct total number of 15 students = 1406 - 9 = 1397

So the correct average of these 15 numbers is = 1397 / 19 = 73.52

The actual average of these 19 students is 73.5

Alternate Method 

Given: 

The average number of 19 students is 74

But by mistake, he writes the number 65 instead of 56

Calculation:

So, total increased value = 65 - 56 = 9

So total average increased = 9 / 19 = 0.47

The correct average was 74 - 0.47 =  73.5

The actual average of these 19 students is 73.5

$\frac{{10}}{{21}}, \div ,1\frac{1}{{14}},,{\rm{of}},\frac{5}{3}, - ,\frac{5}{3}, \times ,\frac{1}{{10}}, + ,\frac{9}{{28}}, \div ,\frac{3}{7},,{\rm{of}},\frac{6}{5}$
