Answer 2

17 boys need 35.59 days to do so.

Step-by-step explanation:

Since we have given that

Number of boys = 11

Number of days they need to finish the task = 55

If the number of boys = 17

We need to find the number of days they need to finish.

According to question, we get that

$11\times 55=17\times x\\\\605=17x\\\\x=\dfrac{605}{17}\\\\x=35.59\ days$

Hence, 17 boys need 35.59 days to do so.
