Question

a certain sum amounts to rupees 5916 in 3 years and to Rs 6960 in 5 years at simple interest find the sum and the rate percent per annum ​

Answer 1

Answer:

p=4350, r=12%

Step-by-step explanation:

let p=5916

after 2 yrs s.i=6960-5916=1044

in 3 yrs s.i=1044×3/2=1566

so actual principal=5916-1566=4350

let rate=r

1566=4350×r×3/100

r=12%
