Correct Answer - Option 4 : Rs. 500

**Given**

Abhi investment = 4 × Bhanu’s investment

Chetan’s investment = Bhanu’s investment – x%

Total profit earned = Rs. 7000

Abhi’s share in total profit = Rs. 5000

**Formula used**

**Calculation**

Let the investment of Bhanu = Rs. 100a

Then the Investment of Abhi = 4 × 100 a = Rs. 400a

And the investment of Chetan = (100 – x) % 0f 100a

⇒ Rs. (100a – ax)

The ratio profit of their investment = 400a : 100a : (100a – ax)

⇒ 400 : 100 : (100 – x)

Let us assume that the total profit

⇒ 400b : 100b : (100b – bx) = 7000

So Share of Abhi = 5000/7000 = 5/7 = 400/ (600 – x)

⇒ 600 – x = 560

⇒ x = 40

The ratio profit of their investment = 400 : 100 : (100 – 40)

⇒ 400 : 100 : 60

⇒ 20 : 5 : 3

⇒ 20 : 5 : 3

Difference between share of Bhanu and Chetan = 2 × 7000/28

⇒ 500

**∴ Difference between share of Bhanu and Chetan is Rs. 500**
