Question

द सेलिंग प्राइस ऑफ 12 इज इक्वल टू द कॉस्ट प्राइस ऑफ 15 पेंस फाइंड द गेन
परसेंट इन प्रोसेस ​

Answer 1

Answer:

Let the cost price of 1 pen = ₹ 1

So, cost price of 12 pens = ₹ 12

SP of 15 pens = ₹ 15

From the question,

Selling price of 12 pens = cost price of 15 pens

Gain = SP – CP

= 15 -12

= ₹ 3

Gain % = {(gain/CP) × 100}

= {(3/12) × 100}

= {300/12}

= 25%
