k and j
Karen and Jill

k=j%2B2.5j=3.5j
and k%2Bj=49


j=49-k
3.5%2A%2849-k%29=k
3.5%2A49-3.5k=k
3.5%2A49=4.5k
k=%283.5%2A49%29%2F4.5
highlight%28k=38%261%2F2%29

If Karen were 2.5 TIMES AS OLD as Jill,... then
k=2.5j
-
j%2Bk=49
k=2.5%2849-k%29
k=2.5%2A49-2.5k
3.5k=2.5%2A49
k=35

Be VERY CAREFUL when in English you see or use the phrase of the type "Karen is 2.5 times older than Jill".


In English, in distinction from many other languages, it means (LITERALLY !) "Karen is 3.5 times as old as Jill is".
