#1. 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?
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 :
Gain %= (0.70/70*100)%
=1%
#3. A man buys a cycle for Rs. 1400 and sells it at a loss of 15 % what is the selling price of the cycle
A man buys a cycle for Rs. 1400 and sells it at a loss of 15 % what is the selling price of the cycle

=Rs. 1190
#4. 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
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 %
#5. Alfred buys an old scooter for Rs. 4700 and spends Rs. 800 on its repairs if he sells this scooter for Rs. 5800, his gain percent is :
Alfred buys an old scooter for Rs. 4700 and spends Rs. 800 on its repairs if he sells this scooter for Rs. 5800, his gain percent is :
C.P = Rs (4700 800 )= Rs 5500
S.P. = Rs 5800
gain % = (300 / 5500*100 )%
= 5 ⁵⁄₁₁ %
#6. 100 oranges are bought at the rate of Rs . 350 and sold at the rate of Rs .48 per dozen . The percentage of profit or loss is :
100 oranges are bought at the rate of Rs . 350 and sold at the rate of Rs .48 per dozen . The percentage of profit or loss is :
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
#7. when a plot is sold for Rs. 18700 ,the owner loses 15% . At what price must the plot be sold in order to gain 15%?
when a plot is sold for Rs. 18700 ,the owner loses 15% . At what price must the plot be sold in order to gain 15%?
85: 18700 = 115 : x
x = ( 18700 * 115 /85)
25300
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:
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
#11. Some articles were bought at 6 for Rs . 5 and sold at 5 for Rs. 6 gain % is :
Some articles were bought at 6 for Rs . 5 and sold at 5 for Rs. 6 gain % is :
suppose number of article bought= L.C.M of 6 and 5 =30
C.P of 30 articles = Rs.( 5/6*30)
Rs. 25 S.P of 30 articles= Rs ( 5/6*30)
=Rs. 36
Gain % = (11/25/100)%
=44%

Market price be Rs x
85% of x =18.70
x-(18.70*100/85)
=22
