Question

Lalita borrowed some money from praveen at the interest rate of 10% per annum.She repaid her debt by paying ₹13500 after 1 year 3 months.What was the sum of money borrowed by lalita?​

Answer 1

Answer:

Sum borrowed by Lalita = Rs.11983.75

Step-by-step explanation:

P = initial amount

R = rate of interest per cent per year = 10

T = time period in years = 1.25 years

[Note: 1 years and 3 months = 1 years + 3/12 years = 1.25 years]

A = final amount = Rs.13,500

According to formula of compound interest:

A = P(1 + R/100)^T

13500 = P(1 + 0.1)^(1.25)

13500 = P(1.1)^(1.25)

13500 = P*(1.126525)

P = 13500/1.26525

P = 11983.75

Answer 2

Answer:

12000

Step-by-step explanation:

rate =10

time = 1.25 year

A/Q A= P+PRT/100

13500=P+PRT/100

13500=P+P/8

13500= 8P+P/8

13500=9P/8

9P=13500×8

P=13500×8/9

P=1500×8

P=12000
