1. A sum of money with compound interest becomes Rs. 400 in 2 years and Rs.500 in 3 years. Find the sum.

1. Rs 290
2. Rs 256
3. Rs 302
4. Rs 308

Explanation: 2 yr = 400
3 yr = 500
1 yr diff= 100 on 400, interest= 100/400= 25%
2 yr successive of 25%= 56.25%
400/ 56.25 x 100= 256

2. The average of three numbers is 22. The sum of two numbers is 24 and the ratio of these two numbers is 7: 5. Find these three numbers.

a) -6, 30, 42
b) 6, 25, 35
c) 14, 10, 42
d) 4, 20, 42

Explanation: a+b+c= 22*3=66
sum of two numbers is 24; remaining= 66- 24= 42
a+b=24; a/b= 7/5 given;
a=7b/5; put in a+b=24;
7b/5 +b=24; 7b+5b=120; b= 120/12=10
