Question

a dealer purchased 60 items at rs.150 each. he sold one -third of them at loss 6%. at what price each must he sell the remaining article's so as to gain 10% on the whole deal ?

Answer 1

Answer: Rs. 2.95

explanation - >

cost of 60 items = Rs. 150

cost of each item = 150/60 = Rs 2.5

----

cost of 1/3rd (20 items) =  20 x 2.5 = Rs. 50

6% loss of Rs. 50 = Rs. 3

---

remaining items = 40

cost of 40 items = 40 x  2.5 = Rs. 100

---

10% on whole deal (Rs.150) = Rs. 15

Hence, selling price of 40 items to have gain = (15+3(loss)) = Rs. 18  is => 100 + 18 = Rs. 118

selling price of 40 items = Rs. 118

selling price of each item = 118/40 = Rs. 2.95
