Five years ago, the sum of ages of Peter and Carlo is greater than 42. Peters age is three more than thrice Carlos age. What is Peters possible age in 7 years?

Answer:

In 7 years, Peters age can be greater than or equal to 49.

Step-by-step explanation:

Five years ago, the sum of ages of Peter and Carlo is greater than 42. Peters age is three more than thrice Carlos age. What is Peters possible age in 7 years?

                       PAST(5 yrs. ago)         PRESENT            FUTURE (7 yrs.)

Peter                         x - 5                       x = 3y + 3                  x + 7

Carlo                          y - 5                           y                           y + 7

x - 5 + y - 5 > 42

x + y > 52

x = 3y + 3

3y + 3 + y > 52

4y > 49

y > 12.25

round up

y ≥ 13

x ≥ 42

x + 7 ≥ 49

In 7 years, Peters age can be greater than or equal to 49.
