At 8:00 a.m. the bus started at 18mph, that means it will cover 27 miles in 1hr 30 mins that is by 9:30 a.m. Then after staying for 30 mins it started to return at 10 a.m. This time its speed is increased by 50%, i.e. 27mph (18+9), thus it will cover the return journey of 27 miles in 1 hour, 11:00 a.m.
Thus, the answer is (c). 11:00 a.m.

Devendra Marghade 11 years ago

b) 72 minutes

Maths questions=50, Others questions=150
If time spent(in minutes) on other question=x, then time spent on Maths question=2x
Here, (50*2x)+(150*x)= 180, On solving x=18/25
So total time spent on Maths questions=50*2*18/25= 72 min.

let there were x men originally.
then x men can do the work in 10 days.
so 1 man can do the work in 10x days.
again
(x-10) men can do the work in 20 days .
so 1 man can do the work in (x-10)*20 days.
=>10x =(x-10)*20 =>x=20 .so 20 men were originally.

let originally the men =x and total days =10
then total men hours=(10*x)
now total men hours=20*(x-10)
