Question

RAJ bought pens for RS.130 a dozen. He sold it for RS.20 each. what was his profit​

Answer 1

1 dozen = 12 pens

cost of 12 pens = ₹130

S.P of each pen = ₹20

s.p of 12 pens = 12 × 20 = ₹240

profit= 240 - 130 = ₹110

profit % = 110 × 100/130

= 84.6%

Answer 2

1 Dozen = 12 units.

So,

Total CP= (Rs 130)

SP for each pen = Rs 20

So,

Total SP=Rs.(12×20)

Total SP=Rs. 240

So, he gains as SP>CP

Profit=SP-CP

=》240-130

=》110.

S●, [Rs.110] is his profit.
