One day Eesha started 30 min late from home and reached her office 50 min late while driving 25% slower than her usual speed. How much time in min does eesha usually take to reach her office from home?  Choose the correct choice from the following.
A) 22	B) 60	C) 99	D) 17	E) 18
We know that Speed is inversely proportional to time   While she drives 25% slower means she drove at 3434(S)   We know that D = S x T   When speed became 3434(S) then Time taken should be 4343(T)   i.e, She has taken 4343(T) - T extra to cover the distance.   Extra Time = T3T3 = 20 min (as 20 min late due to slow driving)   Actual time T = 60 Minutes   Answer:60
