The total cost of a score of apples and a dozen of oranges is greater than or equal to ₹ 420. The cost of each apple cannot exceed ₹ 15. Find the minimum possible cost of each orange ( in ₹) ( 1 score = 20).A. 9B. 11C. 10D. 12

Answer» Correct Answer - C
Let the cost of each apple = ₹ x.
Cost of each orange = ₹ `y`
`20 x + 12y ge 420 ( therefore `1 score = 20)
To get the minimum cost of orange, the apple cost must be maximum, i.e., ₹ 15
`therefore 20xx 15 + 12y ge 420`
`12y le 420 - 300`
`rArr 12y ge 120`
`y ge 10`
The minimum possible value is 10.
