Question

97. A trader marked his goods at 20% above cost
price. He sold half the stock at the marked
price, one quarter at a discount of 20% on
the marked price and the rest at a discount
of 40% on the marked price. His gain percent
is:
(a) 2%
(b) 4.5%
(c) 13.5%
(d) 15%​

Answer 1

Answer:

= 2%

Step-by-step explanation:

Let C.P. of whole stock = Rs. 100

Then,

Marked price of whole stock = Rs. 120

M.P. of 12 stock = Rs. 60,M.P. of 14 stock = Rs. 30

∴ Total S.P.

= Rs. [60 + (80% of 30) + (60% of 30)]

= Rs. (60 + 24 + 18) = Rs. 102

Hence, gain% = (102 - 100)% = 2%
