Bob is x yrs old
Sister is x+6 yrs old
X+X+6=32
2X+6=32
2X=32-6
2X=26
2X/2=26/2
X=13
Bob is 13 yrs old
Sister is 13+6 yrs
= 19 yrs
13yrs+19yrs = 32 yrs
Now its 100% accurate
You can find the improper fractions of both.
14 1/2=29/2
1 3/5=8/5
Divide the two numbers
(29/2)/(8/5) and you will get 145/16 or 9.0625.
Therefore, you can fit 9 books on the bookshelf.

The study also allows the employment of different designs, thereby paving way to a better patient care.
