I used some basic logic
What 2-digit number and that number reversed add up to 77 ?
16 and 61
25 and 52
34 and 43
Which of these look like logical numbers for father/son ages, and have a difference of 27 ??
You asked for the quickest way.
Could you please explain the quickest way to calculate these questions?
1)Julian's age has the same figures as his dad's with the digits reversed. The sum of their ages is 77 and Julian is 27 years younger than his dad. How old is Julian?
