Question

rupees 3600 for 3 years 4 months at 12.5 percent per annum ​

Answer 1

Answer:

Principal, P = Rs. 3600

Rate, R = 15%

Amount, A = Rs. 4500

Formula used:

Simple interest = (P × R × T)/100

Simple Interest = Amount – Principal

Calculation:

Simple Interest = Amount – Principal

⇒ S.I = 4500 – 3600 = 900

Simple interest = (P × R × T)/100

⇒ 900 = (3600 × 15 × T)/100

⇒ 900 = 540T

⇒ T = 900/540

⇒ T = (5/3) × 12 months

⇒ T = 20 months

∴ The required time is 20 months.
