Answer 2

Fisherman takes 15 days to knit

Fisherman will knit part of net in 1 day = 1/15

Boy takes 12 days to knit

Boy will knit part of net in 1 day = 1/12

Together they will knit net in 1 day = 1/15 + 1/12 = (4+5) / 60 = 9/60

They worked together for 5 days,

So, part of net they knit in 5 days will be = 5 * 9/60 = 45/60 = 3/4

Part remaining = 1 - 3/4 = 1/4

Boy can knit whole net alone in 12 days

Boy will knit 1/4 part of net in = 12/4 days = 3 days

Boy will knit the remaining part alone in 3 days.
