Answer 2

Answer:

The correct iption is (c) 3 years.

Please mark my answer brainliest.

Step-by-step explanation:

Present total age of 4 members =24×4=96+(10×4)=136

Preset total age of 6 members (including 2 children) =24×6=144

So sum of the ages of the two children =144−136=8 yrs.

Thus the ages of the children will be 5 yrs and 3 yrs.

As (5+3=8 and 5−3=2)

So, the youngest child's age is 3 years old.
