Question

f) A invests a sum at 20% per annum for 2 years and B does so at 10% per annum for
3 years. If the amount of simple interest received by them is the same, find the ratio
of the sums A and B invested.​

Answer 1

Answer:

3/4

Step-by-step explanation:

Let Simple Interest be x

let simple interest of A and B be a and b respectively.

x = a * 20 * 2 /100

= 2a/5

x = b * 10 * 3/100

=3b/10

2a/5=3b/10

a/b =3/4
