Numerical Ability
A super fast bus of KSRTC starting from 'Trivandrum' and reaches 'Attingal' in 45 minutes with an average speed of 40 km/hr. If the speed is increased by 10 km/hr how much time it will take to cover the same distance?(a) 34 minutes (b) 36 minutes (c) 38 minutes (d) 40 minutes
dinesh_madhu623

Answer is 36 mins We can approach the problem as followsFirst we have to find the distance we can do so byspeed = 40Time = 45 minshence dt = speed * ttdt = 2 * (15)dt = 30Now the speed can be increased by 10 now the speed is 50tt = dt/speedtt = (30/50) * 60tt = 0.6 * 60tt = 36.0

B) 36 mind=s*ts=40 km/hr=40/60km/mint=45mind=(4/6)*45=30kmnow increased speed= 50 km/hr=50/60 km/mind=30 kmt=d/s = 36 min

It fills at a rate of 2 (i.e) 10,20,40.... 1/16 is filled in 17hr. then it fills as 1/8,1/4,1/2,1.. Hence 17+1+1+1+1=21
