Given : एक वस्तु 720 रुपए में बेची जाए तो 10% की हानि होती है।

To Find :  इसे 900 रुपए में बेची तो कितने प्रतिशत का लाभ होगा  

a. 25%

b. 7.5%

C. 12.5%

d. 10%​

Solution:

क्रय मूल्य = C  रुपए

10% की हानि = (10/100)C  = 0.1C रुपए

विक्रय मूल्य = C - 0.1C = 0.9C रुपए

0.9C = 720

=> C = 800 रुपए

क्रय मूल्य = 800  रुपए

विक्रय मूल्य = 900   रुपए

लाभ = 900 - 800 = 100 लाभ

लाभ   प्रतिशत  = (100/800) * 100

= 12.5

सही विकल्प  C. 12.5%
