(#M40000717) TCS QUESTION Keep an EYE

A bus started from bus stand at 8.00a m and after 30 min staying at destination, it returned back to the bus stand. The destination is 27 miles from the bus stand. The speed of the bus 50 percent fast speed. At what time it returns to the bus stand.

(a) 11a.m (b) 12a.m (c) 10a.m (d) 10.30p.m

Solution

The question is not complete, it should also be given in the question that average speed of the bus is equal to the starting speed of the bus
if we make this correction then answer by RAJAT SHARMA given below is correct

the answer is 11 a.m. ..........
let the initial speed of bus is V.....so it takes time in going T1 = 27/V and speed increases 50 %, while returning so time taken T2 = 27/(1.5V) = 18/V and it stops for 30 mins i.e., (.5 hr),
therefore total time taken T =(27/V)+(18/V)+(.5).
then average speed, V = total dist. traveled / total time
i.e.,V=2*27/T on solving we get V = 18 mph
hence finally time taken while going = 1.5hr + staying time (.5hr.) + time in returning with increased speed of 27 mph (1hr.)
hence total time taken=3 hrs. hence 11a.m.

but if we use the initial speed (18 mph) as a given term, then answer given below by YADEESHKUMAR is correct
ans is a)11am
bus covers 27 miles with 18mph in= 27/18 = 1 hr. 30 min.
it waits at stand = 30min.
after this, speed of return increases by 50 % so 50 % of 18 mph = 9 mph
total speed of returning = 18+9 = 27 mph
then in return it takes 27/27 = 1hr.
thus total time in journey = 1+1.30+0.30 = 3hr
so it will come at 8+3hr=11am.
