Question

At what rate per cent will a sum of RS 1200 amount to RS 1600 in 6 years

Answer 1

Answer:

R=?

R=?P=Rs 1200

R=?P=Rs 1200A=Rs 1600

R=?P=Rs 1200A=Rs 1600T=6 years

SI=PRT/100

A=SI+P

A=PRT/100 + P

A=P(RT/100 + 1)

1600=1200(6R + 1)

4=3(6R + 1)

4=18R + 3

Therefore,

R=$\frac{1}{18}$
