Question

ANYONE HELP ! In Paris metro station, in a week 320 trains arrived. Out of these 5% arrived early and 15% arrived late. How many arrived on time?

Answer 1

256 train or 80% of the trains arrived on time

Explanation:

Total trains that arrived in a week = 320 trains

Late = 5% of 320

early = 15% of 320

On time = 320 - (15 + 5% of 320)

=> 320 - (20% * 320)

=> 320 - 64

=> 256

Therefore, 256 train or 80% of the trains arrived on time

Hope my answer helps :)
