7 stubs can make 1 cigarette
49 stubs will make = 49/7 = 7 cigarettes
So, the vagabond has 7 cigarettes
1 cigarette = 3/4 hours
∴ 7 cigarettes = 7 x 3/4
= 5 1/4 hours
So, the cigarettes will last for 5 hours and 15 minutes
49 stubs will make = 49/7 = 7 cigarettes
So, the vagabond has 7 cigarettes
1 cigarette = 3/4 hours
∴ 7 cigarettes = 7 x 3/4
= 5 1/4 hours
So, the cigarettes will last for 5 hours and 15 minutes

Solution :-
Number of stubs gathered by the Vegabond = 49
To make a new cigarette, number of stubs required = 7
So, total number of cigarettes Vegabond can make with 49 stubs = 49/7
= 7 cigarettes
So, he can make 7 new cigarettes from 49 stubs.
Vegabond smokes 1 cigarette every three-quarters of an hour. It means he smokes 1 cigarette every 45 minutes.
So, 7 cigarettes will last for
⇒ (45*7) minutes.
= 315 minutes or 5 hours and 15 minutes
So, 7 cigarettes will last for 5 hours and 15 minutes.
Answer.
Number of stubs gathered by the Vegabond = 49
To make a new cigarette, number of stubs required = 7
So, total number of cigarettes Vegabond can make with 49 stubs = 49/7
= 7 cigarettes
So, he can make 7 new cigarettes from 49 stubs.
Vegabond smokes 1 cigarette every three-quarters of an hour. It means he smokes 1 cigarette every 45 minutes.

= 315 minutes or 5 hours and 15 minutes
So, 7 cigarettes will last for 5 hours and 15 minutes.
Answer.
Hey Bro, your answer is wrong . Here's the right one
It is a trick question.
The idea is that a stub is equal to 1/7 of a cigarette and that only 6/7 of the cigarette is actually smoked.
So he can start by making 7 cigarettes from the 49 stubs.
After smoking those, he will have 7 more stubs left over to make another cigarette. And when that is done he will have one stub remaining.
Answer:
8 * 3/4 = 6 hours
