A shopkeeper expects a gain of 22½ % on his cost price. If in a week, his sale was of Rs. 392, what was his profit?

C.P = Rs. (100*392/122.50)

Rs. (1000*392/1225)

=Rs. 320

Profit = Rs. (392-320)

= Rs. 72

#2. I gain 70 paise on Rs. 70. My gain percent is :

I gain 70 paise on Rs. 70. My gain percent is :

A shopkeeper purchased 70 kg of potatoes for Rs. 420 and sold the whole lot at the rate of Rs. 6.50 per kg What will be his gain percent

C.P of 1 kg = Rs ( 420 / 70 )

=Rs. 6

S.P of 1 kg= Rs 6.50

gain % = (0.50/ 6*100)%

= 25/3 %

8 ⅓ %

C.P of 1 orange = Rs (350 / 100 )

=Rs .3.50

S.P of 1 orange = Rs ( 48/12 )

=Rs . 4

gain % = ( 0.50 / 3.50*100 ) %

=100 / 75%

= 14 ²⁄₇% gain

S.P =Rs. 25300

#8. The ratio of the cost price and the selling price is 4:5 The profit percentage is :

The ratio of the cost price and the selling price is 4:5 The profit percentage is :

C.P = Rs.  4x

Then S.p =Rs 5x

gain =Rs. (5x-4x)=Rs. x

Gain % = (x/4x*100)%

=25%

#9. If selling price is doubled, the profit triples. Find the profit percent:

If selling price is doubled, the profit triples. Find the profit percent:

C.P. be Rs.x and S.P be Rs. y.

Then, 3(y-x)=(2y-x)

y=2x

profit=Rs.(y-x)

=Rs.(2x-x) =Rs. x

Profit%=(x/x*100)%=100%

#10. On selling 17 balls at Rs.72, there is a loss equal to the cost price of 5 balls. The cost price of a ball is:

(C.P of 17 balls)-(S.P. of 17 balls)=(C.P of 5 balls)

C.P. of 12 balls=S.P of 17 balls =Rs. 720

C.P. of 1 ball = Rs (720/12)

=Rs.60
