Question

principal =? rate=8p.r time=5years interest =120 amount =?
find principal

Answer 1

To find the the principal the formula will be
(I x 100)/(R x T), where I is equals interest, r is equals to rate, t is equals to time, so if you calculate like this - (120 x 100)/(8 X5) then your answer will be means your principal will be300

Answer 2

HERE IS YOUR SOLUTION DOOD

P = ? , R = 8% , T = 5 y , I = 120 , A = ?

P = SI × 100
______
R× T

P = 120× 100
______
8 × 5

P = 12,000
_____
40

P = 300......

A = P - SI

A =300-120

A = 180....

P = 300. A = 180
