Deepika went to a fruit shop with a certain amount of money. She retai...
Given:
- Deepika retains 15% of her money for auto fare.
- She can buy either 40 apples or 70 oranges with the remaining amount.
- She buys 35 oranges.
To find:
How many more apples can she buy?
Solution:
Let's assume that Deepika had Rs. 100 with her.
- She retains 15% of her money for auto fare, which is Rs. 15.
- So, she has Rs. 85 left with her.
Now, we need to find out the cost of each apple and orange.
- Let's assume the cost of each apple is 'a' and the cost of each orange is 'o'.
- If she can buy 40 apples with Rs. 85, then the cost of each apple would be Rs. (85/40) = 2.125.
- If she can buy 70 oranges with Rs. 85, then the cost of each orange would be Rs. (85/70) = 1.214.
Deepika buys 35 oranges, which would cost her Rs. (35*1.214) = Rs. 42.49.
- She had Rs. 85 with her, and she spent Rs. 42.49 on oranges. So, she has Rs. (85 - 42.49) = Rs. 42.51 left with her.
Now, we need to find out how many more apples she can buy with Rs. 42.51.
- The cost of each apple is Rs. 2.125.
- So, she can buy (42.51/2.125) = 19.94 apples.
- Since she can't buy a fraction of an apple, she can buy 19 apples with Rs. 42.51.
Therefore, Deepika can buy 19 more apples.
Hence, the correct answer is option 'D'.
