solve: Tim is K years old and Jennifer is 4 years younger than Tim. find their average age in 3K year's time, in terms of K.

Ans:
Tim's present age = K
Jennifer's present age = K - 4
In 3K years, Tim's age would be K+%2B+3%2AK+=+4%2AK
In 3K years, Jennifer's age would be K+-+4+%2B+3%2AK+=+4%2AK+-+4
Their total age would be 4%2AK+%2B+4%2AK+-+4+=+8%2AK+-+4
So, the average age would be %288%2AK+-+4%29%2F2+=+4%2AK+-+2
Ans: highlight%284%2AK+-+2%29

Hope you got it :)
