100% - 30% = 70% (Green paper)
105 sheets -> 70%
100% -> 105 ÷ 70% × 100% = 150 sheets ( Green and pink paper)
8/8 - 5/8 = 3/8 (Green and pink paper)
3/8 units -> 150 sheets
8/8 units -> 150 ÷ 3 × 8 = 400 sheets
105 sheets -> 70%
100% -> 105 ÷ 70% × 100% = 150 sheets ( Green and pink paper)
8/8 - 5/8 = 3/8 (Green and pink paper)
3/8 units -> 150 sheets
8/8 units -> 150 ÷ 3 × 8 = 400 sheets
