Question

a shopkeeper brought 12 hair clips for Rs. 42 and sold 10 for Rs.40.Find his gain or loss percent​

Answer 1

Answer:

14.28 %

Step-by-step explanation:

CP of 12 hair clips = Rs. 42

CP of 1 hair clip = 42 / 12 = 3.5

SP of 10 hair clips = Rs. 40

SP of 1 hair clip = Rs. 40/10 = Rs. 4

Since SP > CP it was a gain

Gain = SP - CP = 4 - 3.5 = 0.5

Gain% = Gain / CP × 100 = 0.5/3.5 × 100 = 50/3.5 = 14.28 %
