Answer 2

Answer:

Cost Price = 640/- and Gain = 80/-

Step-by-step explanation:

Selling Price = 720/-

Gain % = 12.5

Cost Price = ( 100 / 100 + Gain % ) * Selling Price

CP = ( 100/100 + 12.5 ) * 720

CP = (100/112.5 ) * 720

CP = 72000/112.5

CP = 640/-

Gain = (Gain % * Cost Price ) / 100

Gain = (12.5 * 640 ) 100

Gain = 8000/100 = 80

Thus , Cost Price = 640/- and Gain = 80/-
