Question

Three items are purchased at Rs.450 each. One of them is sold at a loss of 10%. The other two be sold so as to gain 20% on the whole transaction. What is the gain % on these two items ?

• A. 30 %
• B. 35%
• C. 25%
• D. 20%

Answer 1

Answer: (B)

35%

C.P. of one item = Rs. 450, C.P. of three items = 3 x Rs. 450 = Rs.1350
Gain on the whole transaction = 20%

$\therefore$ S.P. of the three items = $\frac{1350\times 120}{100}=Rs.1620$
C.P. of 1 item = Rs. 450, Loss = 10%

$\therefore$ S.P. of that item = $\frac{450\times 90}{100}=Rs.405$
$\therefore$ S.P. of the remaining two items = Rs.1620-Rs.405=Rs.1215

C.P. of these two remaining items $=2\times Rs.450=Rs.900$
$\therefore$ Gain on these two items = Rs.315

Gain % = $\frac{315}{900}\times 100=35\%$
