Answer: 172
Explanation:
<u>Mystery</u>          <u>Science Fiction</u>          <u>Biographies</u>
    4x                  3x
                                        4y                       5y
Science Fiction = 48
3x = 48      ⇒    x  = 16          
4y = 48      ⇒     y  = 12
Mystery: 4x   = 4(16)   = 64
Biographies: 5y   = 5(12)   = 60
Mystery + Science Fiction + Biographies = Total
      64     +          48            +         60        = Total
                                                          172    = Total
