Question

Sonika sells two jewellery boxes for rupees 1400 each. On one she earns a profit of 10% and on the other suffers a loss of 10% .Find her overall profit or loss percent.

Answer 1

Heyy

Find total selling Price:

one box = Rs 1400

two boxes = 1400 x 2 = Rs 2800

Find the cost price of the first box:

Profit = 10%

Selling Price = 100 + 10 = 110%

110% = Rs 1400

1% = 1400 ÷ 110 = 140/11

100% = 140/11 x 100 = Rs 14000/11

Find the cost price of the second box:

Loss = 10%

Selling Price = 100 - 10 = 90%

90% = Rs 1400

1% = 1400 ÷ 90

100% = 140/9 x 100 = Rs 14000/9

Find the total cost price:

Total cost price =  Rs 14000/11 +  Rs 14000/9 = Rs 2828.28

Find the profit:

Profit = 2828.28 - 2800 = Rs 28.28

Find the profit percentage:

Profit Percentage = 28.28/2800 x 100 = 1%

answer: The profit of the 2 article is 1%

Answer 2

so cp= rs1400

profit %=10

so profit=1400*10/100

so 140 rs is the profit  sp=rs1540

loss %=10

so loss=1400*10/100

=rs 140is the loss  sp=rs1260

so sum of costs price=1400+1400 =2800

sum of selling prices = 1540+1260 =2800

so there is no profit nor loss
