Correct Answer - Option 5 : None of these
Given that:
Anu and Daskh are equal investments and Taru invested 1/6 of the total money.
Total profit = Rs. 7200
Formula:
Profit = time × money
The investment ratio is equal to profit ratio
Calculation:
Let the total investment was Rs. 12x
According to the question,
Investment of Taru = 1/6 of 12x = Rs. 2x
Investment of Anu and Daksh are equal i.e. (12x – 2x )/2 = 10x / 2 = 5x
Ratio of their money = 5x : 5x : 2x = 5 : 5 : 2
Ratio of profit = Anu : Taru : Daksh = 5 : 5 : 2 → 12 unit
Now, profit = Rs. 7200
Difference between the profits of Taru and Daksh = 7200 × (5 – 2)/12
⇒ 7200 × 3/12
⇒ Rs.1800
∴ Difference between the profits of Taru and Daksh is Rs. 1800
