I go with ans A) 21

Jane started baby sitting at 18 years..
now she is 32.
But she stopped baby sitting 10 years earlier.

Atmost half her age, means, the max age of child could have been 9.

now 32-18 years have passed so 14 years.

The oldest child's age can maximum 23.

The question is current age of youngest child, which will be less than 23.. so the options c, d, e are eliminated.

only A) 21 is less than 23.

Vote for A :-)

She began with 18 so the youngest child could have been 9 years old that time. Now she is 32, 14 years older, so as the child.

I thnik it is A.

The question ask for 

What is the current age of the  youngest child  that Jane could have baby-sat? 

that means any number less that 23 (the highest age), only A is less that 23, and so the answer

vbang · Answer

I agree with B.

The youngest child Jane could have baby sat would be when Jane was the youngest ( and able to baby sit). That would be 18. Therefore, the child would have been 9. Since Jane is now 32, 14 years have passed which would make the child's age 14 + 9 = 23.

Guys,

The main clue here is 'Atmost'.. which means the maximum.

So the age of the youngest child cannot be more than 23, but less.
Since we have 21, I think it more appropriate.

Lets see what is the OA & OE.

Jane 18 19 20 21 22 
Baby 9 10 10 11 11 
So 11+10=21 the answer is A

believe2 · Answer

I agree with 23.
the Q is asking - What is the current age of the  youngest child that Jane could have baby-sat  - This does NOT mean the youngest as of today BUT the youngest at the time of baby sitting. Hence the ans = 9 + 14=23

andy_gr8 · Answer

9 should be the age of the eldest child as per the question stem..Isnt it?

The youngest child can be 1 yr old.In that case 1+14=15, which is not in options..Can anyone explain?

andy_gr8 · Answer

The min and max age of child can be 15 and 23, So anything that comes in between should be the answer..In that case A

Wouldn't this translate to her potentially baby-sittiing anyone less than or equal to half her age?

"she only baby-sat children that were, at most, half her age." 

Example-If she was 22, half her age is an 11 year old ,however, in theory, the child could have been minutes old when she baby-sat. 10 Years + X Minutes is still a 10-Year old.

Can someone explain how to rule this out, with the wording provided in the stem
