Question

Ramesh invested 20% more than Suresh. Suresh invested 10% less than Harish. If the total sum of their investment is 17880, how much amount did Harish invest?

a) Rs. 6000
b) Rs. 8000
c) Rs. 10000
d) Rs. 12000

Answer 1

According to the given information, Harish invested Rs. 5940 and not any of the provided options.

Step-by-step explanation:

Let's assume that the amount Suresh invested is x rupees.

According to the given information, Suresh invested 10% less than Harish, so Harish invested x + (10% of x) = x + 0.1x = 1.1x rupees.

Ramesh invested 20% more than Suresh, so Ramesh invested x + (20% of x) = x + 0.2x = 1.2x rupees.

The total sum of their investments is given as 17880 rupees, so we can write the equation:

x + 1.1x + 1.2x = 17880

Combine like terms:

3.3x = 17880

Divide both sides by 3.3:

x = 17880 / 3.3

Solve for x:

x = 5400

So Suresh invested 5400 rupees and Harish invested 1.1x = 1.1 * 5400 = 5940 rupees.

Therefore, Harish invested Rs. 5940 which is not provided in the options. Hence, we can conclude that the given options are incorrect.
