Question

what is the answer to this??​

Answer 1

Answer:

(i)12%

(ii)Rs. 1344

(iii)Rs. 14049

Step-by-step explanation:

Principal= Rs. 10000

Time=3 years

Rate=?

Amount after 1 year= 11200

Amount=P*(1+R/100)^T

=>11200=10000*(1+r/100)

=>11200/10000=1+r/100

=>112/100=1+r/100

=>112/100-1=r/100

=>12/100=r/100

=>r=12

So, rate=12%

Interest for second year=12%of 11200=1344

Amount for second year=11200+1344=12544

Interest for third year=12%of 12544=1505(1505.28)

Amount for third year=12544+1505=14049
