Hope this helps!
LiftA= u m/s ( upwards)
LiftB= -u m/s(downward)
Velocity A relative to B= V lift A- V lift B=8m/s
u-(-u)=8
u=4m/s
Lift A= 4 m/sec
Lift B= -4m/sec
For someone standing on first floor will be stationary W.r.t to the lift.
V lift A relative to Man= V liftA - V man= 4m/s
V lift B relative to Man= V lift B- V Man= -4 m/s
With cross multiplication you can find that they are the same. In both equations, x would be 100.

Answer:
Correct answer: x = 4
Step-by-step explanation:
If I saw your fractions right it's like this:
(2 + x) / (5 + x) = 2 / 3 => 3 (2 + x) = 2 (5 + x) => 6 + 3 x = 10 + 2 x
3 x - 2 x = 10 - 6 => x = 4
We will check
2 + 4 / 5+ 4 = 6 / 9
When we divide both numerator and denominator
with 3 we get 2/3
God is with you!!!
