Solution
Cost price of 1 refrigerator = Rs 12000
∴ Cost price of 10 refrigerators = 10 × 12000 = Rs 120000
Money spent on transport = Rs 5000
Total cost price = cost of 10 refrigerators + transport charges
= 120000 + 5000
= Rs 125000
Indrajit wants a profit of Rs 20000.
∴ Selling price of 10 refrigerators = Profit + Total cost price
= 20000 + 125000
= Rs 145000
∴ Selling price of 1 refrigerator = 145000 ÷ 10 = Rs 14500
`")"overline145000"(145000"`
