Expenditure of Godrej = x × 100/(100 + 60) = 5x/8
Expenditure of Samsung =x × 100/(100 + 50) = 2x/3

= 15 : 16

 

2. The expenditure of Samsung in the year 2004 is what percentage of its income in that year?

Ans:3
Let the expenditure of Samsung be x.
Income = x × 160/100

Expenditure of Godrej = 98 × 100/100 + 40 = 9800/100 + 40
= 70 1akh
Expenditure of Samsung = 85
Income of Samsung = 85 × (100 + 40)/100 = 11900/100

Sum = 70 + 119
= 189 lakh

 

4. What is the percentage increase in the per cent profit of Godrej from the year 2004 to 2005?
