100% + 40% = 140%

75 Neave's pens : Lee's pens = 35 : 25
80% =
80100 =
45 Ryan's pens : Neave's pens = 28 : 35
Lee's pens: Ryan's pens = 25 : 28 (a)
Neave's pens + Ryan's pens = 35 u + 28 u = 63 u
Lee's pens = 25 u
63 u - 25 u = 304
38 u = 304
1 u = 304 ÷ 38 = 8
Number of Neave's pens
= 35 u
= 35 x 8
= 280 (b)
Answers: (a) 25 : 28; (b) 280
