Question

What sum will amount to Rs 4590 at 12% per annum simple interest in 3 years

Answer 1

Given amount= Rs 4590
           rate of interest = 12%
           time = 3 years
Let principle = P Rs
S.I = P*T*R/100
S.I = P*3*12/100
S.I = 36 P/100
amount = principle + interest
4590 = P + 36 P/100
4590 = 136 P/100
P = 4590*100/136 = Rs 3375
Sum (principle) = Rs 3375

Answer 2

Answer:

Rs.3375

Step-by-step explanation:

Let principal be x

Amount = 4590

Simple interest = 4590-x

Time = 3 years

Rate of interest = 12%

$SI = \frac{P \times R \times T}{100}$

$4590-x = \frac{x \times 12 \times 3}{100}$

$x=3375$

Hence the principal is Rs.3375
