Answer 2

• Pens are bought at 12 for a rupee sold at 9 for a rupee. Find the gain or loss %.
• Pens are bought of 12 for a rupee
• Cost price(c.p) of the 12 pens=Re. 1
• Cost price (c.p) of 1 pen=Rs. 121

Now,

• Selling price(s.p) of 9 pens=Re. 1
• Selling price(s.p) of 1 pen=Rs. 91

• Gain=s.p−c.p

• Rs. [ 9 / 1 − 12 / 1 ]

• Rs. [ 36 / 4−3 ]=Rs. 1 / 36

• = Gain%= c.p / Gain ×100= 1 / 21 / 36 / 1 ×100= 362

• = 3/ 100
