एक वस्तु को 2,100 रुपये में बेचने पर अर्जित प्रतिशत लाभ उसी वस्तु को 1,460 रुपये में बेचने पर हुई प्रतिशत हानि के बराबर है।

प्रयुक्त सूत्र:

माना वस्तु का क्रय मूल्य (CP) x रुपये है।

लाभ प्रतिशत = हानि प्रतिशत

लाभ = विक्रय मूल्य (SP) - क्रय मूल्य (CP)

हानि = क्रय मूल्य (CP) - विक्रय मूल्य (SP)

गणना:

माना क्रय मूल्य (CP) x रुपये है।

2,100 रुपये में बेचकर अर्जित लाभ:

लाभ = 2,100 - x

1,460 रुपये में बेचने पर हुई हानि:

हानि = x - 1,460

चूँकि लाभ प्रतिशत हानि प्रतिशत के बराबर है:

(2,100 - x) / x × 100 = (x - 1,460) / x × 100

⇒ 2,100 - x = x - 1,460

⇒ 2,100 + 1,460 = 2x

⇒ 3,560 = 2x

⇒ x = 1,780

20% लाभ कमाने के लिए, विक्रय मूल्य (SP) होना चाहिए:

विक्रय मूल्य = क्रय मूल्य + क्रय मूल्य का 20%

SP = 1,780 + 1,780 का 20%

SP = 1,780 + 0.20 × 1,780

SP = 1,780 + 356

SP = 2,136

20% लाभ कमाने के लिए वस्तु को 2,136 रुपये में बेचा जाना चाहिए।
