If the expenditure of A and B in 2011 were equal and total income of A and B was Rs. 116 L . What was the total expenditure of A and B in the same years ?

Options

A. Rs. 84 L
B. Rs. 83 L
C. Rs. 80L
D. Rs. 40 L

Answer

C

Explanation

For A
`40=(I-E)xx(100)X)`
`40E=(I-E)100`
`2E=5I-5E`
`5I=7E`
for B
`50=(116-I-E)xx(100)/(E)`
`E=2(116-I-E)`
`E=232-2I-2E`
`2I=232-3E`
`I=(232-3E)/(2)`
`7//5E=((-232-3E))/(2)`
`14E=1160-15E`
`E=(1160)/(29)=40`
`2E=80`
