Answer 2

The given question is A person borrowed Rs.600 @ 3% per annum S.I and Rs.800 @ 4½ % per annum on the agreement that the whole sum will be returned only when the total interest becomes Rs.246.

we have to find the number of years, after which the borrowed sum is to be returned

There are four options, they are a) 2 years b) 3 years c) 4 years d) 5 years

The solution to the given question is found by the method given below.

let the time period be y.

According to the data given in the question, the statement will become

(600* 3%*y)+(800*4.5%*x)=246

18x+36x=246

54x=246

x= 246/54

x= 4.55.

Thus

$4 \times \frac{1}{2}$

Four and half years is the answer.

Therefore, the final answer to the given question is 4.5 years.

The correct option to the given question is option D.
