Question

A sum of money becomes 7/6 of itself in 3 years at a certain rate of simple interest. The rate per annum is ?

A) 45/7 % B) 50/9 % C) 51/7 % D) 47/ 9 %

Answer 1

Answer:

50/9 %

Step-by-step explanation:

Let's the sum of money (Principal) =Rs- x

A=Rs- 7/6

T=3yrs

S.I=?

A=P+S.I

S.I=A-P

S.I=7/6-1 =7-6/6= 1/6

Therefore,S.I=1/6

T=3yrs

P=x

R=?

we know that,R=S.I ×100/P×T

R=1×100/6×x×3

R=1×50/3×x×3

R=50/9%

Hence the Rate =50/9 % .
