Question : 34 of 35

Marks: +1, -0

Expenditure of company 'B' in 2006 was 90% of its expenditure in 2005. Income of Company 'B' in 2006 was what per cent of its income in 2005?

Solution:

Let expenditure of company B in 2005 = Rs. x; then

I_ 1

(Income)

= x+35/100x=27/20x

Since, expenditure of company B in 2006

=90/100×x=9/10x

I_2

(Income)

=9/10x+45/100×9/10x

=9/10x+81/200x=261/200x

Hence, required percentage

={261/200x}/{27/20x}×100

=290/3=96 2/3%
