Question
Cost of one dozen apples, one dozen pears and one dozen oranges are Rs. 480. If the cost of apples is double than oranges and cost of pears half than oranges what is cost of apples?A.300B.400C.275D.250
Solution
Let's solve the problem step by step:
- Let's assume the cost of one dozen oranges is x rupees.
- According to the given information, the cost of apples is double the cost of oranges. So, the cost of one dozen apples would be 2x rupees.
- Similarly, the cost of pears is half the cost of oranges. So, the cost of one dozen pears would be 0.5x rupees.
- Now, we know that the total cost of one dozen apples, one dozen pears, and one dozen oranges is 480 rupees.
- Therefore, we can write the equation: 2x + 0.5x + x = 480.
- Simplifying the equation, we get 3.5x = 480.
- Dividing both sides of the equation by 3.5, we find that x = 480/3.5 = 137.14 (approximately).
- Since we need to find the cost of apples, which is 2x, we multiply 2 by 137.14 to get 274.28 (approximately).
- Therefore, the cost of apples is approximately 274.28 rupees.
So, the correct answer is C. 275 rupees.
