Question

Sum of ages of two friends is 40. Before 5 years product of their ages was 250. Show that these statements cannot be true.

Answer 1

Answer:

Not possible, because if the sum is 20 years, then 4 years ago the sum would have been 12 years .

The greatest number we can reach by multiplying two numbers is the square of half of the number , so the greatest number here is 36 . Hence we cant reach 48. ;)
