Question

in how many years will be Rs. 15000 will be doubled at the rate of 12 1/2 p. c. p. a​

Answer 1

Answer:

P=15000

R=12.5%

A=30000 (100 will double.... =200)

SI=A-P

=30000-15000

=15000

SI=PNR/100

15000=(15000*N*12.5)/100

15000=150*N*12.5

15000/150*12.5=N

8=N

Therefore 15000 will double itself in 8 years

Answer 2

It will take 5.8 years to double at the rate of 12 1/2 p. c. p. a​

Step-by-step explanation:

Principal = Rs.15000

Amount gets doubled

Amount = Rs.30000

Rate of interest =$12\frac{1}{2} = 12.5\%$

Formula : A = P(1+r)^t

30000 =15000(1+\frac{12.5}{100})^t

2=(1+\frac{12.5}{100})^t

t=5.8

Hence It will take 5.8 years to double at the rate of 12 1/2 p. c. p. a​
