दिलेले आहे:

विक्री किंमत = 1540 रु. जेव्हा तोटा = 30%

संकल्पना:

मूलभूत नफा आणि तोटा संकल्पना.

वापरलेले सूत्र:

विक्री किंमत  = खरेदी किंमत × (1 - तोटा %/100)

विक्री किंमत = खरेदी किंमत × (1 + नफा %/100)

गणना:

 टीव्हीची खरेदी किंमत = 1540/(1 - 30/100)

= 1540/0.7 = 2200 रु.

म्हणून,

विक्री किंमत जेव्हा नफा 30% = 2200 × (1 + 30/100) =  2860 रु.
