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
