Sum invested at CI become 6500 after 6 years and rs 7800 further 2 years after then Sum for again further 2 year Period would be Rs 9360
Step-by-step explanation:
A certain sum invested at compounded interest becomes rs.6500 after a period 6 years and rs.7800 after a further period of 2 more years
=> principle after 6 Years = 6500
Amount after 2 Years of 6 Years ( total 8 years) = 7800
=> 7800 = 6500 * ( 1 + r/100)²
=> ( 1 + r/100)² = 7800/6500
=> ( 1 + r/100)² = 6/5
=> ( 1 + r/100)² = 1.2
Amount after further two years
= 7800 ( 1 + r/100)²
= 7800 * 1.2
= 9360
The amount due after a further period of 2 more years is Rs 9360
