Question

There was 90 runners in the first half 2/5 dropped out I the second half 2/3 dropped out how many finished the race

Answer 1

Answer:

18 Runners finished the race

Step-by-step explanation:

Given in question

Number of runners taken part in race = 90

Now in first half , $\frac{2}{5}$ drpped

i.e $90times(\frac{2}{5} )$ = 36

so left runners in first half = 90- 36 = 54

again in second half 54 runners are there, but of them again $\frac{2}{3}$ dropped

So, $54 times(\frac{2}{3} )$ = 36

Thus runner left in second half = 54 -36 = 18

Hence the number of runner finished the race = 18    Answer
