the sugar is sold at rupees 5.4 per kg at a loss of 10% at what price should it be sold per kg to earn a profit of 20%

7.2 rupees

Step-by-step explanation:

Given that at a loss of 10 percent which is 90% price, we have sugar sold at 5.4 rupees per k.g

Hence, at 100 percent we have => 5.4 × (100 ÷ 90 )= 6 rupees per kg.

Therefore, at 100 percent, where we have 6 rupees per kg, to make a profit of 20% we have

6 rupees per kg x 120% = 6 × 1.2 = 7.2 rupees per kg.

Hence, the final answer is 7.2 rupees per kg to make a profit of 20%.
