Question

एक वस्तु 10% के लाभ पर बेची गई। यदि इसे 20% कम् मूल्य पर खरीदकर रे
10 अधिक पर बेचा जाता, तो 40% का लाभ होता, तो वस्तु का क्रय मूल्य क्या होगा?​

Answer 1

उतर :-

माना वस्तु का क्रय मूल्य Rs.100x है l

तब,

→ क्रय मूल्य = Rs.100x

→ लाभ = 10%

→ विक्रय मूल्य = (100x * 110)/100 = Rs.110x

अब,

→ 20% कम में खरीदने पर क्रय मूल्य = (100x * 80)/100 = Rs.80x

→ लाभ = 40%

→ विक्रय मूल्य = (80x * 140)/100 = Rs.112x

दिया हुआ है कि,

→ 112x - 110x = Rs.10

→ 2x = 10

→ x = 5

अत,

→ वस्तु का क्रय मूल्य = Rs.100x = 100 * 5 = Rs.500 (Ans.)
