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?
Answer & explanation
Correct answer: option 2
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
