(12) 1:3
(13) 18% is 3/4 of remainder. So Monday plus remainder is 24% of the books. Therefore 342 is 76%. So total no of books is 450.

Age difference is always the same.
2 units = 24
1 unit = 12
3 units = 36
36 - 10 = 26 years old

Please don't feel bad, Tricia. Cheer up! We all make mistakes, but the most important thing is that we learn from our mistakes and we improve thereafter. I have made so many mistakes that they are strewn all over this forum, so I reckon my skin has grown just that bit thicker. No biggie. :)
