दिया गया है:

विक्रय मूल्य = 1540 रुपए, जब हानि = 30%

अवधारणा:

सामान्य लाभ और हानि की अवधारणा

प्रयुक्त सूत्र:

विक्रय मूल्य = क्रय मूल्य × (1 - हानि %/100)

विक्रय मूल्य = क्रय मूल्य × (1 + लाभ %/100)

गणना:

टीवी का क्रय मूल्य = 1540/(1 - 30/100)

= 1540/0.7 = 2200 रुपए

अतः,

30% लाभ पर विक्रय मूल्य = 2200 × (1 + 30/100) = 2860 रुपए
