Kamal is 17 years older than Gina. Gina is 3 years younger than Rachelle. If the sum of their ages is 77, how old is Gina?

Answer : Gina's age is 19 years.

Step-by-step explanation:

Kamal is 17 years older than Gina. Gina is 3 years younger than Rachelle.

Let Gina's age be x years

So Kamal’s age will be = x + 17

Rachelle’s age = x + 3

the sum of their ages is 77, Accordingly

x + x + 17 + x + 3 = 77

3x + 20 = 77

3x = 77 - 20

3x = 57

x = 57/3

x = 19

Thus Gina's age is 19 years,

Kamal’s age x + 17 = 19 + 17 = 36 years

Rachelle’s age x + 3 = 19 + 3 = 22 years

Gina = 19 years old

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
