Question

Amir buys 40 balls for 2000 rupees. He sells 15 of these at a profit of 20%. He sells the remaining for 40 rupees each. What is the total gain% or loss%.

Answer 1

c. p. of 1 ball =2000/40 = 50

so c. p. of 15 balls =750

s.p. of 15 balls=750+750×20%=900

s.p. of remaining 25 balls=25×40=1000

so total s. p. =1000+900=1900

thus loss =₹100

total loss% = 100×100/2000=5% ans.

Answer 2

Dear Student,

● Answer -

5 % loss

● Explanation -

Cost price of each ball is -

Cost price = 2000/40

Cost price = 50 Rs

Amir sells 15 balls at 20%.

Selling price = 50 × (100+20)/100

Selling price = 60 Rs

Remaining toys are 40-15 = 25 balls.

So total income from selling balls is -

Total selling price = 15 × 60 + 25 × 40

Total selling price = 1900 Rs

Total gain/loss % is -

Gain/loss % = (1900-2000)/2000

Gain/loss % = -5/100

Gain/loss % = -5 %

Hence, total loss is 5 %.

Hope this helps...
