Question

The cloth shop has announced a reduction in price by 25%. How many shirts priced at Rs 28 should buy to avail a total reduction of at least Rs 40?

Answer 1

At least 6 shirts should be brought to avail a total reduction of Rs 40.

Explanation:

The marked price of each shirt = Rs 28

Discount offered = 25%

So, 25% of marked price 28 =
`(25)/(100)  * 28 = 7`

⇒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}}`

= 40 Rs /7 Rs = 5. 71 ≈ 6

So, at least 6 shirts should be brought to avail a total reduction of Rs 40.
