LC MRT:
Children = 25%
Adults= 75%
B MRT:
Children left: 80% of 25% = 20%
Adults left = 85% of 75% = 63.75%
a) Children left = 640
Therefore 20% = 640.
At LC MRT = 100 ÷ 20 x 640 = 3200 children.
b) Total adults left in B MRT = 63.75 = 63.75÷ 20 x 640 = 2040
Total passenger = Children + Adults
= 640 + 2040
=2680 passenger.
Hope this helps
