Answer 2

Given :- In 2018 , a person spent half the time working , a third in sleeping and one - eighth in cooking . He spent the rest of the time exercising .

Solution :-

→ Person spent time in working = (1/2).

→ Person spent in sleeping = (1/3) .

→ Person spent time in cooking = (1/8)

So,

→ Total time he spent in working, sleeping and cooking = (1/2) + (1/3) + (1/8) = (12 + 8 + 3)/24 = (23/24) .

Now, it has been said that he spend the rest of the time exercising .

Therefore,

→ Time he spent on exercise = 1 - (Total time he spent in working, sleeping and cooking) = 1 - (23/24) = (1/24) .

Now, we know that,

→ One day = 24 Hours.

→ 1 year = 365 days.( since 2018 is not a leap year.)

Hence,

→ Total hours he spent on exercise = (1/24) of (24 * 365) = 365 Hours. (Ans.)

∴ Total hours he spent excercising is 365 Hours.
