Question

gautum takes a loan of rs 64000 at25% per annum as rate of interest. Find the simple interest he has to pay at the end of 9 months

Answer 1

Given principal = 64000, Time = 9 months = 9/12 years , Rate of interest = 25%.

We know that SI = PRT/100

⇒ (64000 * 25 * 9)/(100 * 12)

⇒ (14400000)/(1200)

⇒ 12000.

Therefore, simple interest = 12000.

Hope this helps!

Answer 2

Given , principal(P) = Rs 64000

Rate(R) = 25 % p.a

Time(T) = 9 months = 9 /12 yr = 3 /4 yr

since, we know that

simple interest = P × R × T /100

=( 64000 × 25 × 3/ 4 ) / 100

=64000 × 75 / 400

=160× 75

=Rs 12000

therefore , the simple interest he has to pay at the end of 9 months = Rs 12000.
