[ "A)60km/hr", "B)80km/hr", "C)100km/hr", "D)120km/hr" ]
B
Explanation : let distance between A and B be D km and real speed of the car be S km/hr First time car takes 90 minutes more and second time car takes 75 minutes more than scheduled time. So, T1 – T2 = 15/60 = 100 15/60 = [100/s + (D -100)/(3s/4)] – [160/s + (D – 160)/(3s/4)] Solve this D will be cancelled and S comes ...

the ans is quite simple N-M but since the ans is not given, the best way to 'find' the correct option is to plug in the numbers. For my work, i took the following numbers: L = 100 M = 10 N =20. So basically, L beat G by 10 meters. Now whatever options comes close to the figure 10 is the right ans.. looking the the opio...

Walking 6/7th of his usual speed, a man is 12 minutes too late. The usual time taken by him to cover that distance is :
[ "A)1 hr 20 min", "B)1 hr 10 min", "C)1 hr 11 min", "D)1 hr 12 min" ]
D
Sol. New speed = 6/7 of usual speed. New time = 7/6 of usual time ∴ [7/6 of usual time] - (usual time) = 1/5 hr. ⇒ 1/6 of usual time = 1/5 hr ⇒ usual time = 6/5 hr = 1 hr 12 min. Answer D
