Answer 1

Answer:

3 year hence the age of two friend will be X and Y years respectively. therefore the sum of their ages two year ago was X + Y -10 years.​

Step-by-step explanation:

3 Year Hence age of one friend = X

Current age of Friend = X - 3

2 Year Before age of that friend = X - 3 - 2 = X - 5

3 Year Hence age of another friend = Y

Current age of That Friend = Y - 3

2 Year Before age of that friend = Y - 3 - 2 = Y - 5

Sum of their ages two year before = X -5 + Y - 5

= X + Y - 10

sum of their ages two year ago was X + Y -10 years
