Dharan bought a donkey and a carriage for Rs.3000. He sold the donkey at a gain of 20% and the carriage at a loss of 10%, thereby gaining 2% on the whole. Find the cost of the donkey? 
by

1 Answer

Answer :

Let the cost price of the donkey be Rs ‘X’

 Then cost price of the carriage = Rs(3000-X)

 20% of X – 10% of (3000 – X) = 2% of 3000

 X/5 – (3000-X)/10 = 60

 2X – 3000 + X = 600

 X = 1200

 Hence cost price of the donkey = Rs.1200

Description : Murugan sold a book at a loss of 40%. If the selling price had been increased by Rs.200, there would have been a gain of 10%. What was the cost price of the book?

Last Answer : Let cost price be Rs ‘x’  Then (110% of x) – (60 % of x) = 200  (110x/100) - (60x/10) = 200  110x – 60x = 20000  X = 400  So cost price of the book = Rs.400

Description : Sridevi sells an article at a profit of 50%. If she had bought it at 40% less and sold it for Rs.21.50 less, She would have gained 60%. Find the cost price of the article.

Last Answer : 1st selling price=150% of x = 150x/100 = 15x/10 New Cost price=60% of x = 60x/100 = 6x/10  2nd selling price = 160% of 6x/10 = 160/100 * 6x/10 = 96x/100  Therefore 15x/10 – 96x/100 = Rs.21.50  X=Rs.39.81  Therefore cost price of the article = Rs.40 (approx.)
