A sum of money amounts to rs.6690 after 3 years and to rs.10,035 after 6 years on compound interest. Find the sum.

A. 3467

B. 4560

C. 4460

D. 7890

Correct Answer :

C. 4460


Let the sum be rs.P.then


P(1+R/100)3=6690…(i) and   P(1+R/100)6=10035…(ii)


On dividing, we get (1+R/100)3=10025/6690=3/2.


Substituting this value in (i),we get:


P*3/2=6690 or P=(6690*2/3)=4460


Hence, the sum is rs.4460.
