If the simple interest on a sum of money at 6%for 10 years is equal
to the simple interest on another sum of money for 7 years at 5%, then
find the ratio of two sums.
f interest for 5 years is less

Answer 1

Answer:

Step-by-step explanation:

R= 6%

t = 7 years

principal =P

SI = P*R*t/100. eq(1)

again,

R' = 5%

t' = 9 year's

P' = principal

SI' = P'*R'*t'/100. eq(2)

a/q

P*6*7/100=P'*5*9/100

Required ratio P/P' = 18/21
