Question

A sum of money was invested at 6percentage per annum for 3 years and ₹9990 at 8 percentage per annum single interest for 5 years yields the same simple interest. Find the sum invested

Answer 1

Step-by-step explanation:

Let the sum be Rs.P.then

P(1+R/100)^3=6690..(i) and P(1+R/ 100)^6=10035..(i)

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.
