Rs.1000. If Merchant A computes his profit on cost price, while Merchant B
computes his profit on selling price, they end up making profits of 25%
respectively. By how much is the profit made by Merchant B greater than that of
Merchant A?
Answer: (b)
Solution:
profit on cost price = 1000-(100/125)*1000= 200
(selling price-cost price)
profit on selling price = (25/100)*1000 = 250
difference = 50
Question: A person sells a book
with a loss of 10%. If he sells it for 104 rupees more, he earns a gain of 10%.
Now, what will be the cost price of the book?
(a) 400 rupees
(b) 520 rupees
(c) 640 rupees
(d) 840 rupees
(a) 400 rupees
(b) 520 rupees
(c) 640 rupees
(d) 840 rupees
Solution: Let
cost price be x,
selling price =90% of x(since he is having 10% loss)
90% of x +104 = 110% of x (since he is having 10% profit)
90% of x + 104 = 110% of x
110/100 * x - 90/100 * x = 104
x/5=104
x= 104*5=520
selling price =90% of x(since he is having 10% loss)
90% of x +104 = 110% of x (since he is having 10% profit)
90% of x + 104 = 110% of x
110/100 * x - 90/100 * x = 104
x/5=104
x= 104*5=520

has gained 12.5% profit but 30 guest were absent. He charged same cost , lost
100 rs. What is the per meal cost?
Answer: 30
Solution: If x is the cost of 1 meal, then
240x*100/112.5 = 210x+100
solving it, we get
x= Rs 30.
Question: A shop keeper sell an article gets profit of 20%
had he bought it for 20% less and sold it for Rs 120 less he would have still
bought profit of 20% what is the cost price of article.

Solution:
let cost
price=x; selling price=120%(x)
new cost price=80%(x) i,e 20% less than previous
cost price
new selling price= 120%(x)-120 therefore from the
question
but new selling price = 120%(80%x) therefore from
cost price
120%(80%(x))=120%(x)-120
x=500
Question: A watch was sold at a profit of 15%. If its cost

according to the question
1.15x=0.95x*(110/100)+21

160=4x
x=40
hence 2x=80
so total no are 80dozens
