Answer 2

66 pens will last for 18 days for 15 kids.

Given,

45 kids complete 22 pens in 2 days.

To Find,

The number of days 66 pens last for 15 kids.

Solution,

The number of days taken by a kid to complete 1 pen

22 Pens completed in 45 x 2 days

=> 22 pens completed in 90 days

=> 1 Pen complete in 90/22 days

=> 1 Pen complete in  45/11 days

Now, the number of days required to complete 66 pen

1 Pen complete in  45/11 kid days

66 Pen complete in  66 x  45/11  = 270 kid days

Divide by 15 kids to find the number of days

Number of days = 270/15  = 18

Hence, 66 pens will last for 18 days for 15 kids.
