Question

a sum of money at simple interest amounts to Rs.800 in 2years and to Rs.1200 in 6years. The sum is​

Answer 1

Amount in 2 years = Rs.800 ===> eqn 1

Amount in 6 years = Rs.1200 ==> eqn 2

Substract eqn 1 from eqn 2

Amount in 6 years - Amount in 2 years = Interest in 3 years

1200 - 800 = Interest in 3 years

Interest in 3 years = 400

Interest in 2 years = 400 / 3 × 2

= 266.666667

Principal = Amount - Interest

===> 800 - 266.666667

===> 533.33
