Question 58

Rita's present age is four times her daughter's present age and two-thirds of her mother's present age. The total of the present ages of all of them is 154 years. What is the difference between Rita's and her mohter's present age?

Solution

Let Rita's age be R.
Mother's age = 3R/2
Daughter's age = R/4
Total = R + 3R/2 + R/4 = 11R/4 = 154 => R = 56
So, difference of ages = R/2 = 28 years
