To find
• The cost price and the selling price of each refrigerator.
Solution,
= let the C.P of one refrigerator = xRs
= C.P of other refrigerator = 28500-x
Profit = 10% of x = 10x/100 = x/10
S.P = x+x/10 = 11x/10 Rs
Loss = 10/100 of 28500-x
= 2850/10-x
= S.P = (28500-x/10)
= 28500-10x-2850+x/10
= 256500-9x/10
= 11x/10 = 256500-9x/10
= 11x+9 = 246500
= 20x = 256500
x = 256500/20
x = 12825
C.P of one refrigerator = 12825Rs
Other refrigerator = 28500-12825
= 15675rupees.
