The following line graph gives the annual percent profit earned by a Company during the period 1995 - 2000.

Percent Profit Earned by a Company Over the Years.

%Profit =	Income - Expenditure	x 100
	Expenditure

If the income in 1998 was Rs. 264 crores, what was the expenditure in 1998?

Rs. 104 crores

Rs. 145 crores

Rs. 160 crores

Rs. 185 crores

Answer: Option

Explanation:

Let the expenditure is 1998 be Rs. x crores.

Then, 65 =	264 - x	x 100
	x

	65	=	264	- 1
	100		x

x =	264 x 100	= 160.
	165

Therefore Expenditure in 1998 = Rs. 160 crores.

%Profit = (Income-Expenditure)/Expenditure * 100 .
Let expenditure=x.
65=(264-x)/x * 100,
65= (264/x - 1) * 100,
65 = (264/x)*100 - 100,
65+100x = 264*100,
x=(264*100)/165,
x=160.

Can anyone please tell me how 65 became 165 in denominator.

Jegapriya said: 1 decade ago

65/100+1 = 264/x.

65+100/100 = 264/x (cross multiplication).

165/100 = 264/x.

x = 264x100/165.

x = 160.

Can anyone please explain from where that -1 came?

Lovely said: 6 years ago

To all who are asking why to take x as 1.

If we make the equation separate in two parts then 2nd part will become x/x, i.e. = 1.
