Answer 1

Answer:

R = 5%

Step-by-step explanation:

Let the rate of Interest = R

Given That

Principal Amount (P) = ₹ 15,000

No. of Years(T)= 13 - 5 = 8 years

Interest paid = Difference of amount paid and principal amount

Interest paid = 21000-15000 = ₹6000

According the formula

Interest paid = PTR/100

₹6000 = 15,000 × 8 × R /100

6000 × 100 = 15000 × 8 × R

6 × 1000 × 100 = 15 × 1000 × 8R

Cancel the 1000 on both sides

6 × 100 = 15 × 8R

R = 6 × 100/120

R = 5 %

Rate of Interest = 5%
