Eric had
112 as many stamps as Charlie. Charlie had twice as many stamps as Carl. If Eric had 240 stamps fewer than Carl,
- how many stamps did Eric have?
- how many stamps did they have altogether?
(a)
Number of stamps that Eric had = 1 u
Number of stamps that Charlie had = 12 u
Number of stamps that Carl had = 12 u ÷ 2 = 6 u
Number of stamps that Eric had fewer than Carl
= 6 u - 1 u
= 5 u
5 u = 240
1 u = 240 ÷ 5 = 48
Number of stamps that Eric had
= 1 u
= 48
(b)
Total number of stamps that they had
= 1 u + 12 u + 6 u
= 19 u
= 19 x 48
= 912
Answer(s): (a) 48; (b) 912
