310The number of pens that Gillian had at first is repeated. Make the number of pens that Gillian had at first the same. LCM of 10 and 7 is 70.
Number of pens that Roshel had in the end
= 21 u + 40 u
= 61 u
Number of more pens that Roshel had than Gillian in the end
= 61 u - 30 u
= 31 u
Number of more pens that Roshel had than Gillian in the end in percent
=
3130 x 100%
≈ 103.3%
Answer(s): 103.3%
