P says “Q committed the crime.”
Q says “S committed the crime.”

distance traveled by first car (with speed of 50 km/h) = 50*1 = 50 km
And, distance traveled by second car (with speed of 60 km/h) = 60*1 = 60 km

So, distance between these cars = 60 - 50 = 10 km 
distance traveled by first car (with speed of 50 km/h) = 50*2 = 100 km
And, distance traveled by second car (with speed of 60 km/h) = 60*2 = 120 km

So, distance between these cars = 120 - 100 = 20 km 
→ (distance traveled by second car) - (distance traveled by first car) = 20 km
→ (S2*T) - (S1*T) = 20 
→ (60*T) - (50*T) = 20 
→ 10*T = 20 
→ T = 2 
→ 10*x = 8*(x + 150) 
→ 10*x = 8*x + 8*150
→ 2*x = 8*150
→ x = 8*150 / 2
→ x = 600 
10*x = 10*600 = 6000 
= 10+20+20 
= 50 
= 80+20+20+40 
= 160 
= (50/160)*100
= 31.25 % 
= 60 + 80 + 30 + 38 + 2 + 10 + 5
= 225 
x*0.25 = 225
= 225/0.25
= 900 
Request by X: Due to pollen allergy, I want to avoid a wing next to the garden.
Request by Y: I want to live as far from the washrooms as possible since I am very much sensitive to smell.
Request by Z: I believe in Vaastu and so I want to stay in South-West wing.
