A and her grandfather differ in their ages by 46 years.  After 5 years, if the sum of their ages is 132 years, their present ages are?

30 , 90 38 , 84  29 , 89 33 , 88

38 , 84

Sum of ages at present = 132 - (2 × 5) = 122 Difference of ages = 46 Grandfather's age = \(\frac{122 + 46}{2}\) = 84 A's age = 122 - 84 = 38 So, Present ages are 38 , 84
