Some man is going to some place. after traveling for 2 hrs, his car got punctured. his driver took 10 minutes to change the tyre. For safety, he drove the car with the speed of 30mph.they were late by half an hr. The driver told that if the problem had occurred after traveling 30 miles, they would have come late only by 20 minutes.

they were late by 30 min. out of 30 min 10 min gone for changing tyre. they drove 20 min extra due to low speed (30 mph). as per driver if the problem had occurred after traveling 30 miles, they would have saved 10 min. it tells car earler speed was 36 mph.they drove 2 hr with 36 mph and 2hr with 30 mph total 132 mile

x y z
+ a b
--------
cdef
means the out put is 4 digit number,by adding 2 digits at max we can get a carry of 1
so x+1=cd;i.,e x=9 and c=1,d=0
similarly
x y z
- a b
--------
b g a
we know x=9 and so it may give one carry so b=8
and from both we can get some equations like
10+z-8=a=>2+z=a
z+8=10+f
and y+a=e+9
10+y-a=g
trial and error method satisfying all the conditions from equations
it gives result up to my knowledge
