Rakesh bought 50 article for Rs 20000.He sold 20 of them at a gain of 15%. At what rate must he sell the remaining article so as to gain 30% on the whole?
Answers
cost price of 50 articles = Rs 20,000
cost price of 1 article = 20,000/50
=Rs 400
cost of 20 Articles=20 × 400 = Rs 8000
selling price of 20 articles
=8000 + 15 % of 8000= 8000 + 1200
=Rs 9200
required gain=30 % of the total C.P
_______________________________
=30% of 20,000 = 30 × 20,000 /100
=Rs 6000
Required selling price:
_______________________________
=20,000 + 6000 = 26,000
Remaining selling price to gain 30% on the whole
=26,000 - s.p of 20 articles
=26,000 - 9200 = Rs 16800
remaining articles to sell:
_______________________________
=50 - 20 = 30 articles
C.P of remaining (30) articles
=30 × 400 = Rs 12000
profit=16800 - 12000 = Rs 4800
profit % = profit / c.p × 100
=4800/ 12000 × 100 = 40%
therefore,
he must sell the remaining articles at the rate of 40% to gain 30 % profit on the whole.
