Question

A man works for 10 hours a day. He works only 5 days in a week. Find the total number of hours worked by the man in two years. (There are 52 weeks in a year.)

Answer 1

Number of hours a man works in a day
= 10
Number of days a man works in a week
= 5
Number of hours a man works in a week
= $5\times 10$
= 50
Number of hours a man works in a year
= $52\times 50$
= 2600
Number of hours a man works in two years
= 2600 x 2
= 5200

So, man works for 5200 hours in a year
