Answer 2

Dear Student,

◆ Answer -

10 years

● Explanation -

# Given -

P = Rs 1200

Total = Rs 1800

r = 5 %

# Solution -

Total payback by simple interest is -

Total = P (100 + r×t) / 100

1800 = 1200 (100 + 5×t) / 100

1800 × 100/1200 = 100 + 5t

150 = 100 + 5t

5t = 150 - 100

5t = 50

t = 50/5

t = 10 years

Hence, 10 years are required.

Thanks dear. Hope this helps you...
