Question

what principle will amount to rs 900 in 6 years at 10% simple interest.?

Answer 1

Heya...Here is your answer --

Time = 6 yrs

Rate = 10%

Amount = ₹900

Let the principal be ₹x

SI = PRT/100

SI = x × 10 × 6/100

SI = 6x/10

SI = 3x/5

Principal + SI = Amount

x + 3x/5 = 900

5x+3x/5 = 900

8x/5 = 900

8x = 900×5

x = 900×5/8

x = 1125/2

x = ₹562.5

HOPE IT HELPS...!!
