Question
Pradeep invested 20% more than Mohit. Mohit invested 10% less than Raghu. If the total sum of their investment is Rs. 17880, how much amount did Raghu invested? Rs. 5000 Rs. 6500 Rs. 6000 Rs. 7500
Solution
Let's denote the amount Raghu invested as R.
According to the problem, Mohit invested 10% less than Raghu, which means Mohit invested 0.9R.
Pradeep invested 20% more than Mohit, which means Pradeep invested 1.2 * 0.9R = 1.08R.
The total sum of their investments is Rs. 17880, so we can set up the following equation:
R (Raghu) + 0.9R (Mohit) + 1.08R (Pradeep) = 17880
Solving this equation will give us the amount Raghu invested.
2.98R = 17880
Divide both sides by 2.98:
R = 17880 / 2.98
R = Rs. 6000
So, Raghu invested Rs. 6000.
