A) 1.5 hours
B) 1.75 hours
C) 2 hours
D) 2.5 hours

Answer 1

To find out how long it takes Mani to shampoo one carpet, divide the total time (7 hours) by the number of carpets (4). The result is 1.75 hours per carpet.

Step-by-step explanation:

The question is asking us to find out how long it takes for Mani to shampoo one carpet if it takes him 7 hours to shampoo 4 carpets. To find this, we can divide the total amount of time by the number of carpets. We take the 7 hours and divide it by 4 carpets to get the time taken for one carpet.

Dividing 7 hours by 4 carpets:

• 7 ÷ 4 = 1.75

Thus, it takes Mani 1.75 hours to shampoo one carpet, which corresponds to option B.
