To find the value-added tax (VAT), we need to calculate the tax paid and charged, then find the difference.

Step 1: Calculate the tax paid on purchase

Tax paid = 5% of Rs. 52900 = 0.05 * 52900 = Rs. 2645

Step 2: Calculate the tax charged on sale

Tax charged = 7% of Rs. 53500 = 0.07 * 53500 = Rs. 3745

Total parts = 3 + 2 = 5

Ahsan’s share = (2/5) × 45,000 = Rs. 18,000

Explanation

Let's denote Umar's current age as x.

Noor's current age = x + 8

After 3 years:

Umar's age = x + 3

Noor's age = x + 8 + 3 = x + 11

According to the problem:

x + 3 = 1/3 * (x + 11)

3(x + 3) = x + 11

3x + 9 = x + 11

2x = 2

x = 1
