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
