Let present age of A = x

If A is 4 years less than that of B , then age of B = x+4

60% more of B's age 4 year before = 1.6 x

If Age of C after 4 years is 60% more of B's age 4 year before, then present age of C = ( 1.6 x - 4 )

Sum of present age of A and C = x + ( 1.6x -4 ) = 48  .....................(1)

From above expression, we get x = 20

Age of A = 20  year; Age of B = 24 year;

Average age of A and B = 22 year ;

Data given below is related to daily routine [study time (in hours), entertainment time (in hours) and rest time (in hours)] of three students A, B and C.    Daily routine (24 hours) = Study time + Entertainment time + Rest time   A's study time is 1 hour less than B's study time and A's rest time is 7 hours more than his entertainment time. Ratio of A's entertainment time to B's entertainment time is 1: 2. Average of study time of A, B and C is 6 hours. Average of rest time of A and B is 9 hours.
