We know that, Cost of fresh oranges+ cost of packaging = Total cost Earlier, Let the cost of fresh orange be Rs 1, then cost of packaging = Rs 0.4 ∴ Total cost = 1 + 0.4 = 1.4 Later, Cost of fresh orange and that of packaging would be Rs 1.3 and 0.2 respectively. ∴ Total cost = 1.3 + 0.2 = 1.5 ∴ Percentage increase in cost- Hence, the required increment in cost is 7.14%.Related questions
