## The compound and the simple interests on a certain sum at the same rate of interest for two years are Rs.11730 and Rs.10200 respectively. Find the sum.

A. Rs.18000
B. Rs.17000
C. Rs.18500
D. Rs.17500

The simple interest for the first year is 10200/2 is Rs.5100 and compound interest for the first year also is Rs.5100. The compound interest for the second year on Rs.5100 for one year

So rate of the interest = (100 * 1530)/ (5100 * 1) = 30% p.a.
So P = (100 * 10200)/ (30 * 2) = Rs.17000

A. Rs.140
B. Rs.120
C. Rs.130
D. Rs.110

A. Rs.3502.80
B. Rs.3052.40

## Rayan invested certain amount for two rates of simple interests at 6% p.a. and 7% p.a. What is the ratio of Rayan’s investments if the interests from those investments are equal?

A. 4: 3
B. 3: 2
C. 6: 5
D. 7: 6

Let x be the investment of Rayan in 6% and y be in 7%

x(6)(n)/100 = y(7)(n)/100
=> x/y = 7/6
x : y = 7 : 6

A. Rs.21.60
B. Rs.24.00
C. Rs.25.20

## Shohaib invested Rs. 8000 in a scheme for 2 years at compound interest rate 5% p.a. How much amount will Shohaib get on maturity of the fixed deposit?

A. Rs. 8600
B. Rs. 8620
C. Rs. 8800
D. None of these

Correct Answer: D. None of these

= Rs. 8820

## What will be the compound interest on a sum of Rs. 25,000 after 3 years at the rate of 12% p.a.?

A. Rs. 9000.30
B. Rs. 9720
C. Rs. 10123.20
D. Rs. 10483.20

Amount = [25000 * (1 + 12/100)3]

= 25000 * 28/25 * 28/25 * 28/25 = Rs. 35123.20
C.I. = (35123.20 – 25000) = Rs. 10123.20

## A man saves Rs. 200 at the end of each year and lends the money at 5% compound interest. How much will it become at the end of 3 years?

A. Rs. 565.25

Amount = [200(1 + 5/100)3 + 200(1 + 5/100)2 + 200(1 + 5/100)]

= [200 * 21/20(21/20 * 21/20 + 21/20 + 1)] = Rs. 662.02

A. Rs. 16,500
B. Rs. 16,525.50
