Explanation

A man bought a flat for Rs.820,000. He borrowed 55% of this money from a bank. How much money did he borrow from the bank?

Total Amount = 820,000

Bought from Bank = 55%

               = 820,000 x 55/100

                               = 451,000

Explanation

Ahmed earns Rs. 45,696 in a year. What is his average monthly income?

= 45,696/12

= 3808

Explanation

Let us consider that the actual cost of the article is "x".

Since the decrease in price = 24 %= 0.24

x - 0.24 x = 912

0.76 x = 912

x = 912 / 0.76

x = 1200

Explanation

To evaluate this expression, we need to follow the order of operations (PEMDAS):

Calculate 25% of 30%: 0.25 x 0.30 = 0.075

Calculate 0.075 as a percentage of 45%: 0.075 x 0.45 = 0.03375

So, the correct answer is: 0.03375

Explanation

40 is subtracted from 60% of a number, the result is 50

(60/100) * X – 40 = 50

6X = 900

X = 150

Explanation

Explanation

Multiply 10 x 12 x 15 = 1800

Explanation

Four years ago, the average age of A, B, and C was 25 years.

This means that the total age of A, B, and C four years ago was 25 x 3 = 75 years.

Since then, all three have aged 4 years, so their total age now is 75 + 4 + 4 + 4 = 87 years.

Five years ago, the average age of B and C was 20 years.

This means that the total age of B and C five years ago was 20 x 2 = 40 years.

Since then, both B and C have aged 5 years, so their total age now is 40 + 5 + 5 = 50 years.

Now, we know that the total age of A, B, and C is 87 years, and the total age of B and C is 50 years.

So, A's current age is 87 - 50 = 37 years.

The correct answer is: 37 years

Explanation

Five years ago, the average age of P and Q was 15 years.

This means that the total age of P and Q five years ago was 15 x 2 = 30 years.

Since then, both P and Q have aged 5 years, so their total age now is 30 + 5 + 5 = 40 years.

The average age of P, Q, and R today is 20 years, so the total age of P, Q, and R is 20 x 3 = 60 years.

We already know that the total age of P and Q is 40 years, so R's age must be 60 - 40 = 20 years.

After 10 years, R's age will be 20 + 10 = 30 years.

So, the correct answer is: 30 years
