Fabian had
112 as many pens as Flynn. Flynn had thrice as many pens as Charlie. If Fabian had 144 pens fewer than Charlie,
- how many pens did Fabian have?
- how many pens did they have altogether?
(a)
Number of pens that Fabian had = 1 u
Number of pens that Flynn had = 12 u
Number of pens that Charlie had = 12 u ÷ 3 = 4 u
Number of pens that Fabian had fewer than Charlie
= 4 u - 1 u
= 3 u
3 u = 144
1 u = 144 ÷ 3 = 48
Number of pens that Fabian had
= 1 u
= 48
(b)
Total number of pens that they had
= 1 u + 12 u + 4 u
= 17 u
= 17 x 48
= 816
Answer(s): (a) 48; (b) 816
