Answer 1

Answer:

Rs. 9484.4

Step-by-step explanation:

For first 3 years:

P = 12000

R = 5%

n = 1

t = 3

A = 12000(1+0.05)^3 = 13891.5

For next 4 years:

P = 13891.5

R = 6%

n = 1

t = 4

A = 13891.5(1+0.06)^4 = 17537.7

For last 3 years:

P = 17537.7

R = 7%

n = 1

t = 3

A = 17537.7(1+0.07)^3

A = 21484.4

Total Interest = Final Amount - Principal

= 21484.4 - 12000

= 9484.4
