Solution:

Cost price of 150 pens = 150 × 12 = 1,800
Sale price of 150 pens =

1,800 + 15/100 × 1,800

= Rs 2,070
Cost price of 50 pens = 50 × 12 = Rs 600
Sale price of 60 pens =

600 + 10/100 ×600

= Rs 660
Sale price of 100 pens = 2,070 - 660 = Rs 1,410
Percentage gain on 100 pens

={1410-1200}/1200 ×100= 17 1/2%
