Problem: Problem: walking at 5 / 6 th of its usual speed a cab is 15 mnts late . find its usual time to cover the journey ? 
Options: a ) 25 m , b ) 45 m , c ) 32 m , d ) 75 m , e ) 62 m
Solution: d
Explanation: New speed = 5 / 6 th of usual speed new time = 6 / 5 th of usual time 6 / 5 ut - ut = 15 m ut / 5 = 15 m ut = 75 m answer is d

Problem: Problem: a can do a work in 15 days b in 14 days and c in 16 days . if they work on it together then in how many days required to complete the work ? 
Options: a ) 3360 / 210 , b ) 3360 / 21 , c ) 3360 / 674 , d ) 3360 / 240 , e ) 3360 / 224
Solution:
c
