Answer 2

Answer:

Lucy's age now = 37years

Step-by-step explanation:

Given,

When Lisa was 6 years old, Lucy's age = half of Lisa's age = 3years

That is when Lisa is 6 years old, Lucy is 3 years old

We can conclude that difference in the ages of Lisa and Lucy = 3 years

Lucy's age = Lisa's age - 3

When Lisa is 40 years

Lucy's age = Lisa's age - 3 = 40 -3 = 37

∴Lucy's age now = 37years
