Question

on a certain sum,the interest paid by manoj after 3 years is ₹1,350at 5% p.a. find the sum borrowed by manoj

Answer 1

interest=₹1350
rate=5%
time=3years
sum/principal=P(let it be p)
S.I=
$s.i = \frac{p \times r \times t}{100 } \\ 1350 = \frac{p \times 5 \times 3}{100} \\ 1350 = \frac{p \times 15}{100} \\ 1350 = \frac{p \times 3}{20} \\ 1350 \times \frac{20}{3} = p \\ 9000 = p$
$1350 = \frac{p\times 3}{20} \\ 1350 \times \frac{20}{3} = p \\ 9000 = p$
so, sum=₹9000

Answer 2

Answer:

Rs 9000

Step-by-step explanation:

Given,

the interest paid by manoj after 3 years is ₹ 1,350 at 5% p.a.

Let the amount borrowed by Manoj = P

Formula of simple interest ,

S.I = ( P * R * T ) / 100

Where ,

P = Principle amount

R = Rate of interest

T = Time

Rs 1350 = ( P * 5 * 3 ) / 100

P = Rs 9000

Hence the amount borrowed by Manoj is Rs 9000
