## Word problems on Percentage 4 - Problems

Problem 1 :

Sum of the cost price of two products is \$50. Sum of the selling price of the same two products is \$52. If one is sold at 20% profit and other one is sold at 20% loss, find the cost price of each product.

Solution :

Let x and y be the cost prices of two products.

Then, we have

x + y  =  50 -----(1)

Let us assume that x is sold at 20% profit.

Then, the selling price of x is

=  120% of x

=  1.2x

Let us assume that y is sold at 20% loss.

Then, the selling price of y is

=  80% of y

=  0.8y

Given : Sum of the selling price of the same two products is \$52.

1.2x + 0.8y  =  52

Multiply each side by 10 to get rid of the decimal.

12x + 8y  =  520

3x + 2y  =  130 -----(2)

Solving (1) and (2), we get

x  =  30

y  =  20

Hence, the cost prices of two products are \$30 and \$20.

Problem 2 :

A computer store used a markup rate of 40%. Find the selling price of a computer game that cost the retailer \$25.

Solution :

Selling price (S.P)  =  (100 + M)%  C.P

Here, M  =  40, C.P  =  \$25.

Then, we have

S.P  =  (100 + 40)%  25

S.P  =  (100 + 40)%  25

S.P  =  140%  25

S.P  =  1.4  25

S.P  =  \$35

Hence, the selling price is \$35.

Problem 3 :

A golf store pays its wholesaler \$40 for a certain club, and then sells it to a golfer for \$75. What is the markup rate?

Solution :

Cost price (C.P)  =  \$40

Selling price (S.P)  =  \$75

Mark up value  =  75 - 40  =  \$35

Mark up rate  =  (35/40) ⋅ 100 %  =  87.5 %

Hence, the mark up rate is 87.5 %

Problem 4 :

A store uses a 40% markup on cost. Find the cost of a pair of shoes that sells for \$63.

Solution :

Selling price (S.P)  =  (100 + M)%  C.P -----(1)

Here, S.P  = \$63,  M  =  40

Substitute the above values in (1).

(1)-----> 63  =  (100+40)%  C.P

63  =  140%  C.P

63  =  1.4 ⋅ C.P

Divide each side by 1.4

45  =  C.P

Hence, the cost of a pair of shoes is \$ 45

Problem 5 :

A product is originally priced at \$55 is marked 25% off. What is the sale price?

Solution :

Selling price (S.P)  =  (100 - M)%  L.P -----(1)

Here, L.P  =  \$55,  M  =  25

Substitute the above values in (1).

(1)-----> S.P  =  (100 - 25)%  55

S.P  =  75%  55

S.P  =  0.75  55

S.P  =  41.25

Hence, the selling price is \$ 41.25 Apart from the problems on percentage given above, if you need more problems on percentage, please click the following links.
