HCL Profit and Loss Quiz-1

Cost of 1 apple = 30/3 = 10

Cost for 100 apple = 10 x 100 = 1000

Gain 20%.

So, the required rate = 1000 x (120/100) = 1200

Profit %= 100(SP - CP)/CP = 100 x (6000-5000)/5000 = (100 x 1000)/5000 = 20%

So, 30 CP = x SP

=>\frac{30}{x} =\frac{SP}{CP}

=>\frac{30}{x} -1 = \frac{SP}{CP} - 1

=>\frac{(30-x)}{x} =\frac{(SP-CP)}{CP} 

=>\frac{(x-30)}{x} =\frac{40}{100}

=>100x - 3000 = 40x

=>100x - 40x = 3000

=>60x = 3000

=>x = 3000/60 = 50

Total expense on car = 4000 + 600 = 4600

SP = 6000

So, profit = 6000 - 4600 = 1400

Gain % = 100(Profit)/CP = (1400/4600) x 100 = 30.4%

CP of 5 chocolate = 1 rs.

SP of 5 chocolate = 125/100 = 5/4 rs.

So, in 1 rs. He will sell (5x4)/5 = 4 chocolates.

SP = CP x (120/100)

=>CP = SP x (100/120)

=>CP = 60,000 x (10/12) = 50,000

SP : CP = 6:5

=>SP/CP = 6/5

=>(SP-CP)/CP = (6-5)/5

=>Profit % = (1/5) x 100 = 20%

Cost price = 12000

Loss = 10%

So, Selling price = 12000 x (90/100) = 10800 rs

Total expense = 20000 + 600 + 400 = 21000

Gain 10%

So, Selling price = 21000 x (110/100) = 23,100

In the case, if profit and loss is given same then in that case we can put the direct formula given as = (profit x loss)/100 = (25*25)/100 = 6.25% loss
