InfyTQ Profit and Loss Quiz 3

Correct option: D

Solution
Cost price of TV = 14,000
Loss of 20%

Loss % = \frac{CP -SP}{CP} \times 100

0.2  =\frac{ 14000 - SP }{14000}

0.2  x 14000 =14000 - SP

SP =11200

Solution: Profit % = \frac{S.P.-C.P}{C.P.}\times 100


25 = \frac{250-C.P}{C.P.}\times 100

25C.P.= 25000 – 100C.P.

125C.P. = 25000

C.P. = Rs. 200

Correct Option: B

Solution

C.P. of 1 dozen eggs is Rs. 420 => cost of 12 dozen eggs is 12 x 420 = Rs. 5040

S.P. of 1 egg is Rs. 40

S.P of 1 dozen eggs is 12 x 40= Rs. 480

S.P. of 12 dozen eggs = Rs. 12 x 480 = 5760

Profit % = \frac{5760 – 5040}{5040}\times 100

= \frac{720}{5040}\times 100

=14.28%

Correct option: A

Solution

Loss% =20%

=> 0.8 C.P. = S.P.

=> 0.8 C.P. = 50

C.P. = 62.5

To make a profit of 10%

S.P. = 1.1 x 62.5

S.P. = Rs. 68.75

Correct Option: A

Solution: Selling price of the product = 15,000

Let the price of product after 25% discount on Marked price be ‘x.’

0.75 M.P. = x

After 15% additional discount,

0.85x = 15000

x = Rs. 17,647

• 0.75 M.P. = 17647


• M.P. = \frac{17647}{0.75}


• M.P. = 23529.33 ≅ Rs. 23,530

Solution: Cost price of the Car = 250,000

Cost of repair = 50,000

Total cost of car = 250,000 + 50,000 = 300,000

Profit % = 20 %

Selling price = 1.2 x 300,000 = 360,000

Solution: C.P. of a book sold at a profit of 10% = \frac{550}{1.1} = Rs. 500

C.P. of a book sold at a loss of 10% = \frac{550}{0.9} = Rs. 611.11

Total cost price of two books = 500+611.11 = 1111.11

Total selling price of the two books = 550+550 =1100

Loss = 1111.11 - 1100 = 11.11

Loss% = \frac{11.11}{1100} \times  100 = 1.01%

Solution: Let the C.P of the box be ‘x’

x-\frac{1}{16} \times x = 20

16 x-x= 20 \times 16

15x = 320

X= 21.33

Solution: let the cost price of 1000 gm sugar be Rs. 100

Cost price of 800gm sugar = Rs. 80

Profit made by shopkeeper = 100 – 80 = 20

Profit% =\frac{20}{80} \times 100 = 25 %

Solution: Let the actual cost price if motorbike be x

C.P. for motorbike = \frac{85}{100}\times x = \frac{17x}{20}

Profit earned by jugal is 40% on cost price

S.P. = 1.4 \times \frac{17 x}{20}=\frac{23.8 x}{20}

Profit on actual price =  \frac{23.8x}{20}-x = \frac{3.8x}{20}

Profit % = \frac{3.8 x }{20x}\times 100

=3.8 x 5

=19%
