Chapter 4: Algebra Puzzle

• Let d represents drum
• Let c represents clock
• Let p represents pen
• 3p = 48
• p = 48/3
• Therefore, p is 16
• Since 2p + c = 46
• 2p = 16 x 2 =32
• 46 = 2p + c
• 46 = 32 + c
• 14 = c
• Therefore, c is 14

• Since 2p + d = 34
• 2p = 16 x 2 =32
• 34 = 2p + d
• 34 = 32 + d
• 2 = d
• Therefore, d is 2

In conclusion, each pen represents 16, each clock represents 14 and each drum represents 2.
