Question

this year on your 11 th birthday your mother tells you that she is exactly 3 times as old as you are. how old is she?​

Answer 1

Answer:

33

Step-by-step explanation:

If it is your 11 th birthday you are 11 years old.

3 times of x = 3×11

therefore your mother is 33 years old.

Answer 2

Step-by-step explanation:

Son’s age = a

Mom’s age = 3a

3a + 11 = 2 (a + 11)

3a + 11 = 2a + 22

-2a -2a

a + 11 = 22

-11 -11

a = 11

Therefore, initially the son was 11 and his mother 33.

11 yrs later the son will be 11 + 11 = 22 and his mother will be 33 + 11 = 44 making the mother twice as old as the son.
