Question

at what rate percent will a sum of rupess 4000 amount to 5324 in three years​

Answer 1

Answer:

hello dear!

Step-by-step explanation:

Putting the values in the formula

CI= P(1+r/100)^n-P

we get

1324 = 4000[(1+r/100)^3-1]

on solving we get

1324/4000+1=(1-r/100)^3

5324/4000=(1-r/100)^3

1331/1000=(1-r/100)^3

(11/10)^3=(1-r/100)^3

on cancelling cube from both sides we get

11/10=1-r/100

on solving we get

r=10%

hope it helps!!!!!
