CAT 2022 Profit and Loss Problems: Different Types of questions that feature in the topic

In this article, we simply cover the different types of Profit and Loss problems that are based on the concepts of Profit and Loss. In this article, we do not cover any concepts as such and simply focus on the different problem types that feature in various examinations. In this article, you simply practice the different Profit and Loss problem types. For concept articles, refer to the three previous articles for this topic.

Type-1: Consumption – expenditure based

If the price of an item increases by r% ,then the percentage reduction in consumption so that expenditure remains the same ,is

Question 1: If price of sugar increases by 20% ,then the percentage reduction in consumption so that expenditure remains the same will be ?

Solution: To find the percentage reduction in consumption, apply formula

(20/120)x100=50/3%

Type-2:  If the price of a commodity decreases by r% then percentage increase in consumption , so as not to decrease expenditure on this item is

Question 2:  If the price of sugar falls down by 10% ,by how much percent must a householder increase its consumption , so as not  to decrease expenditure in this item ?

Solution: To find the percentage increase in consumption, apply formula:-

{10/(100-10)} x 100 = 100/9%

Type-3: If a reduction of x% in price enables a person to buy y kg more for Rs A,  then the

Question 3: A reduction of 10% in the price enables a person to buy 2 kg more wheat for Rs 30.Find the reduced and the original price of wheat.

Solution:

Reduced Price = (x/100y)A

{(30 x 10)/(100 x 2)} Rs. = Rs. 3/2

Original Price = [x/{(100-x)y}] x  A

[(30 x 10)/{(100 – 10)x2}] = Rs. 5/3

Type-4: Successive profit / loss

When there are two successive profits of x% and y% then the net percentage profit =[x+y+xy/100]

When there is a profit of x% and loss of y% then net percentage profit or loss = [x – y – xy/100]

Note: If the final sign in the above expression is positive then there is net profit but if it is negative then there is net loss.

Question 4: A sells an item at a profit of 20% to B and B sells it to C at a profit of 10%. Find the resultant profit percent .

Solution: When there are two successive profit of x% and y% , net profit percentage

= {x+y+(xy/100)}

= 20+ 10 + {(20 x 10)/100} = 32%

Question 5: A sells an item at a profit of 20%to B and B sells it to C at a loss  of 10%.find the resultant profit percent.

Solution: When there are two successive profit of x% and y% net profit percentage = [x – y – xy/100]

=[20 – 10 – {(20 x 10)/100}] = 8%

Type-5: Goods passing through successive hands

A sells goods to B at a profit of x% and B sells it to C at a profit of y%. If C pays Rs. x for it, then the cost price for A is Rs

Question 6: A sells a good to B at a profit of 20% and B sells it to C at a profit of 25%.If C pays Rs 222 for it, calculate the  cost price for A is

Solution:  Applying Formula 

(222 x 100 x 100)/(120 x 125)} = Rs. 148

Note :- For loss replace plus sign with minus .

Type-6: When each of the two things is sold at the same price,and a profit of p% is made on the first and a loss of L% is made on the second ,then the percentage gain or loss is:

Question 7. Each of the two cars is sold at the same price. A profit of 20% is made  on the first and a loss of 10% on second.calculate loss/gain %.

Apply formula :-

[{100(20 – 10)-2 x 20 x 10}/{(100+20)+(100-10)}] = 20/7%

Question 8. Two items are sold for Rs 200.The first one is sold at 20% profit and second one at 20% loss. What is the % loss or gain ?

Solution : Apply Formula

As percentage profit is equal to percentage loss so put P=L, we get,%loss = P²/100

=> %loss = (20)²/100 = 4%

Type-7: If cost price of x things is equal to the selling price of y articles, then profit percentage = (x-y/y)*100%

Example 9: The cost price of 18 articles is equal to the selling price of 15 articles. The gain per cent is :

Solution: Profit Percentage : (x-y/y)*100%

Gain percentage : {(18 – 15)/15} x 100

= 3/15 x 100 = 20%

Example 10: The cost price of 25 articles is equal to selling price of 20 ar­ticles. The gain percent is

Solution:

Profit percentage = (x-y/y) * 100%

%Gain = {(25-20)/20} x100 = 5/20 x 100 = 25%
