Question

There were 60 runners to start a race. In the first half of the race, 1/3 of them dropped out. In the second half of the race, 4/5 of the remaining runners dropped out. How many runners finished the race?

Answer 1

08 runners finished the race.

Explanation:

Given that:

Number of runners at the race = 60

Number of runners dropped in first half = 1/3 of 60

Number of runners dropped in first half =
`(1)/(3)*60 = 20`

Remaining runners = 60 - 20 = 40

Number of runners dropped in second half = 4/5 of 40

Number of runners dropped =
`(4)/(5)*40 = 32`

Runners left = 40 - 32 = 08

Hence,

08 runners finished the race.
