Fanny had some pens at first. She gave 26 of her pens to her cousin and 14 of her pens to her friend. After that, her mother gave her another 17 pens. She had 52 pens in the end. How many pens did Fanny have at first?

512 Number of pens left after giving to her cousin and her friend = 5 u
Number of pens left after her mother gave her another 17 pens = 5 u + 17
5 u + 17 = 52
5 u = 52 - 17
5 u = 35
1 u = 35 ÷ 5 = 7
Number of pens that Fanny had at first
= 12 u
= 12 x 7
= 84
