B

Answer: B

Solution

Total age 4 members,10 years ago=(24×4)=96

Total age of 4 members now=(98+10×4)=136

Total age of 6 members now=(24×6)=144

Sum of the ages of 2 children=(144-136)=8 years

Let the age of the younger child be x years

Then the age of the elder child=(x+2)

so,. x+x+2=8

2x=6. x=3

Age of the younger child=3 years
