Option 4 : 45000

**Given: **

Anant invested Rs. 81000 in a business for 8 months and then 4000 more for 4 months. B invested certain amount for 4 months and then increased the invested amount by 5000 for the remaining 8 months. The ratio of their profits was 247 : 130.

**Formula: **

Ratio of Profit = ratios of product of Amount invested and time

**Calculation: **

Let the amounts invested by B for 4 and 8 months respectively be x and x + 5000 respectively.

(81000 × 8 + 85000 × 4)/(x × 4 + (x + 5000) × 8) = 247/130

(247000)/(12x + 40000) = 247/130

x = 40000

The amount invested by B in the last 8 months = x + 5000 = 40000 + 5000 = 45000
