Question

Graham has twice as many books as Bob. Chan has six more books than Bob. If Bob has 푥books, which of the following represents the total number of books the three boys have?

Answer 1

Given :

• Graham has twice as many books as Bob.
• Chan has six more books than Bob.

To find :

• If Bob has x books, which represents the total number of books the three boys have?

Solution :

• Here Bob has x number of books.

• Since Graham has two as many books as Bob, then Graham has 2x number of books.

• Again since Chan has six more books than Bob, the Chan has (x + 6) number of books.

• Therefore total number of books had by the three boys is
• = x + 2x + (x + 6)
• = x + 2x + x + 6
• = 4x + 6

Answer :

• The required representation is (4x + 6).
