23.
now
Max: 20yo
Nancy: 3/5 x 20 = 12yo
in x yrs time,
Max: (20+x)yo
Nancy: (12+x)yo
total age = 20+x+12+x = (32+2x)yo
24.
children: 5/8 of total
adults: 3/8 of total
girls: 3/10 of children
boys: 7/10 of children
= 7/10 x 5/8 = 35/80 of total
35/80 of total = 28
80/80 of total = 28/35 x 80 = 64
total in library = 64
