Question

A sum of money becomes Rs 1100 in 2 years and Rs 1400 in 6 years at S.I. Find the rate of interest?​

Answer 1

Answer:

Interest for 4 yrs=1400-1100 = 300

lyr interest=300/4=75

principal (P) = 1100-150 = 950

rate = 75/950 x loo=7.9% (Appr)

Answer 2

Step-by-step explanation:

Interest for 4 yrs=1400-1100 = 300

lyr interest=300/4=75

principal (P) = 1100-150 = 950

rate = 75/950 x loo=7.9% (Appr)

Difference b/w 3rd yr interest n 2nd interest is 714 - 672 = 42

then we have to find out 42 is how much % on 672 then we will get rate of interest

672*x/100=42

x=42*100/672

x=6 1/4 % = 6.25%
