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

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

Question: A shopkeeper allows a discount of 5 percent to his customers. What price should he mark on an article, the cost price of which is Rs. 800 so that he makes clear profit of 25 percent on his outlay?

Answer: 30

Solution: If x is the cost of 1 meal, then 
240x*100/112.5 = 210x+100

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.

(b) 300

(c) 400

(d) 500

Answer: (d)

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 had been 5% less and it had been sold for Rs. 21 less, than the profit would have been 10%. Find the cost price of the watch

(b) 300

(c) 400

(d) 500

Solution: let the price of the watch is x
it was sold at a profit of 15%
then the price of the watch is 1.15x
again cost had been decreased by 5% i.e 0.95x
according to the question
1.15x=0.95x*(110/100)+21
then x=200

Solution: let total no of mangoes is 2x..
then we profit=sp-cp
160=13*2x-(12x+10x)
160=4x
x=40
hence 2x=80
so total no are 80dozens
