Answer:
Present age of Mahesh = 20 years
Present age of his father = 50 years
 
Let x years before, mahesh's father's age was 4 times of mahesh age
 
x years before, age of Mahesh = (20-x) years
x years before, age of father = (50-x) years
 
hence,   4×(20-x) = (50-x)
 
80 - 4x = 50- x  
 
3x = 30  or  x =10  ;  hence 10 years before fathers age was 4 times of mahesh's age
