Explanation

Let's calculate D:

D = 1 * 10 * 100 = 1000

Now, calculate each term:

D/8 = 1000 / 8 = 125

D/5 = 1000 / 5 = 200

D/4 = 1000 / 4 = 250

D/2 = 1000 / 2 = 500

Sum = 125 + 200 + 250 + 500 = 1075

The sum of the digits of 1075:

1 + 0 + 7 + 5 = 13

Explanation

Given the profit-sharing ratio:

Zubair : Kashif : Aijaz = 2 : 3 : 4

Kashif's share = Rs. 450

Let's find the value of one part of the ratio:

3 parts = Rs. 450

1 part = Rs. 450 / 3 = Rs. 150

Zubair's share = 2 parts

= 2 * Rs. 150

= Rs. 300

Explanation

Let's say the number is x. Its reciprocal is 1/x.

x ÷ 1/x = x * x = x²

The answer is square of a number.

Explanation

Given:

n = (3/2) / (1/4)

To divide by a fraction, we multiply by its reciprocal:

n = (3/2) × (4/1)

= (3 × 4) / 2

= 12 / 2

= 6

So, n = 6.

The answer is 5 and 7.
