Answer:
Profit % = 14.5%
Step-by-step explanation:
Solution,
CP for 60 pens = Rs. 60 × 10 = Rs. 600
Sp for 49 pens = 49 × Rs. 12 = Rs. 588
Sp for remaining pens i.e. 11 pens = 11 × Rs. 9
= Rs. 99
Total SP = Rs. 588 + 99
= Rs. 687
Profit % = SP - CP / CP ×100%
= Rs. 687- 600 / 600 ×100%
= Rs. 87/600 × 100%
= 14.5%
