Since Alisha is present in both. We know that the difference between the two total is the difference in Mohan vs Jane.

Thx but what about b) ?
Sorry, I didn’t see it.
Since we know that the difference is 200.
We can look at the ratio as Mohan has 5 units more than Jane.
So 5units = 200 stickers
1 unit = 40 Stickers
Find the amount of stickers either Jane or Mohan has and subtract 608 or 408 from the answer.
Mohan 9 Units = 360 stickers
Jane 4 Units = 160 stickers
Alisha = 608 - 360 = 248 stickers
OR
Alisha = 408 - 160 = 248 stickers
