Question

find the simple interest on $2500 at 4.5 per cent per annum for 5 years

Answer 1

Heya,  ​  

Simple interest [S.I.] = (P×R×T)/100  

Principal [P] = $2,500

Rate [R] = 4.5 % p.a.

Time [T] = 5 years    

∴ Simple Interest  

= $ (2,500×4.5×5)/100  

= $ (25 × 4.5 × 5)  

= $ 562.5    

Hope it helps !
