Answer:
At least 6 shirts should be brought to avail a total reduction of Rs 40.
Step-by-step explanation:
The marked price of each shirt = Rs 28
Discount offered = 25%
So, 25% of marked price 28 = ![\frac{25}{100} \times 28 = 7](https://tex.z-dn.net/?f=%5Cfrac%7B25%7D%7B100%7D%20%20%5Ctimes%2028%20%3D%207)
⇒Reduction on each shirt is Rs 7
Now, total amount reduction needed = Rs 40
So, number of shirts purchased = ![\frac{\textrm{Total reduction needed}}{\textrm{Reduction on each shirt}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctextrm%7BTotal%20reduction%20needed%7D%7D%7B%5Ctextrm%7BReduction%20on%20each%20shirt%7D%7D)
= 40 Rs /7 Rs = 5. 71 ≈ 6
So, at least 6 shirts should be brought to avail a total reduction of Rs 40.
