A dealer sold three-fourths of his articles at a gain of 20 percent and the remaining articles at the cost price. Find the gain earned by him in the whole transaction.
A20%
B18%
C16%
D15% ✓ Correct
Correct answer: (D) 15% — The answer is 15 percent.
Explanation
★The answer is 15 percent.
★Take the total cost as 100.
★Three-fourths of the goods, costing 75, are sold at 20 percent gain for 90.
★The remaining one-fourth, costing 25, is sold at cost for 25.
★So the total selling price is 90 plus 25, which is 115, on a cost of 100, a gain of 15 percent.
★The other options do not match this value.
★So the answer is 15 percent.
