Question

Q11.In how many years Rs 800 will amount to Rs1152 at a compound interest of
20 p.c.p.a?​

Answer 1

Answer:

Let me Tell you this answer....

Step-by-step explanation:

Present/Original amount= Rs 800

Interest=20%

Let the time be t years,

Amount=Principle x (1+Interest/100)^t

After putting the values,

1152=800 x (120/100)^t

1152/800=(6/5)^t

1.44=(1.2)^t

We can write 1.44 as,

(1.2)^2=(1.2)^t

t=2

So the total time is 2 years.  Hope my answer will help you!!!!!!!!!
