The marked price of a Pant and a T-Shirt are in the ratio of 2 : 3. The shopkeeper gives 40% discount on the Pant. If the total discount on the Pant and the T-Shirt is 40% the discount offered on the T-Shirt is
28 $\dfrac{1}{3}$%
18 $\dfrac{2}{3}$%
26 $\dfrac{2}{3}$%
None of these
Explanation:
Let the marked price of the pant be Rs. 200.
Then marked price of T-Shirt will be Rs. 300.
Discounted price of Pant = 200 × 60/100 = Rs. 120
Let the discounted price of T- Shirt be x.
According to the question,
120 + x = 60/100× (200 + 300)
or, 120 + x = 300
or, x = 180
Discounted offered on the T - Shirt
= 300 – 180/300 × 100 = 40%
Note: If overall discount is 40% and discount on one part is also 40% then naturally the discount on the second part is also 40%.
