Question 89
Certain amount is divided into 3 parts such that those parts yields the equal interest after 1, 2 and 3 years respectively at 4% simple interest per annum. Then the ratio between the three parts respectively is
Solution
Let say,
p,q and r are the three parts.
So,Then the simple interest would be
$$(p×0.04×1)=(q×0.04×2)=(r×0.04×3)$$
$$=k(let say).$$
$$p=25k,q=12.5k and r=(25/3)k.$$
So,
$$p:q:r=25k:12.5k:(25/3)k$$
$$=k:0.5k:(k/3)$$
$$=6:3:2.$$
A is correct choice.
