Profit and loss is an important chapter for competitive examinations. From past few years I am analyzing question papers of banking examinations. Today I am sharing 10 questions that are repeated in the exams.
Ques 1.I sold two hens for Rs. 105 each . On one I lost 25% . On the other I gained 50% . What is the gain or loss on my total outlay ?
Ques 2.Sudhira sold a watch at a profit of 20%. Had she bought it at 10%less and sold it at Rs 30 less, she would still have gained 20% .Find the cost price of the watch.
Ans 2. Let the C.P. of the watch be Rs x.
Gain % in both the cases is the same .
Hence, C.P. of the watch = Rs.250.
Ques 3.I bought eggs at the rate of 5 for Rs 7 and sold them at the rate of 7 for Rs. 10 and made Rs.2450 in the bargain. How many eggs did I deal in ?
Ans 3. Suppose I bought 35 eggs.
C.P. of 35 eggs = Rs. 49, S.P. of 35 eggs = Rs 50
Profit on 35 eggs = Re 1
∴ required number of eggs = 2450/1 x 35 = 85750.
Ques 4.A shop's prices are 25% above cost price, but it allows its customers 12% commission on the amounts of their bills. What is the profit per cent made ?

Ques 7.A man buys oranges at a certain price per dozen and sells them at eight times that price per hundred . What is his gain or loss % ?
Ans 7. Let C.P. of 12 oranges = Re 1
S.P. of 100 oranges = Rs 8
Ques 8.I sold a book at a profit of 12%. Had I sold it for 18 more, 18% would have been gained . find the cost price.
Ques 9.The cost price of 24 articles is equal to the selling price of 18 articles . Find the gain per cent .
