Mean x = Sum of nos. / Count of numbers = 729/9 = 81 = x
Median y = Middle term when number are arranged in ascending order = 83 = y
Mode z = Number which is present maximum number of times = 68 = z
=> x*y*2z = 81*83*2*68 = 914328

A father said to his son, "I was as old as you are at the present at the time of your birth". If the father's age is 46 years now, what was the son's age twenty one years back?
Let the sons current age be x
So fathers age x years back when son was born => 46-x = x
Solving we get x = 23
21 Years back son's age = 23-21 = 2 years
CP of 1 toffees = 665/175 = Rs. 3.8
