Zoe had 56 more pens than Jane. After Jane gave away
13 of her pens, Zoe had five times as many pens as Jane. How many pens did Jane have at first?

Comparing Zoe and
Jane at first |

| Before |
10 u |
3 u |
| Change |

- 1 u |
| After |
10 u |
2 u |
Comparing Zoe and
Jane in the end |
5x2 =
10 u |
1x2 =
2 u |
Number of pens that Jane had in the end is repeated. Make the number of pens that Jane had in the end the same. LCM of 1 and 2 is 2.
Number of pens that Zoe had at first = 10 u
Number of pens that Zoe had more than Jane at first
= 10 u - 3 u
= 7 u
7 u = 56
1 u = 56 ÷ 7 = 8
Number of pens that Jane had at first
= 3 u
= 3 x 8
= 24
Answer(s): 24
