The contents of a certain box consist of 14 apples and 23 oranges. How many oranges must be removed from the box so that 70 percent of the pieces of fruit in the box will be apples?

The contents of a certain box consist of 14 apples and 23 oranges. How many oranges must be removed from the box so that 70 percent of the pieces of fruit in the box will be apples? (a)3 (b)6 (c)14 (d)17 (e)20

Please help me with this one. I'm unable to understand the technique used in the OG. Thanks

As only oranges must be removed then 14 apples which are now in the box must comprise 70% of total # of fruits after removal: 0.7*total=14 --> total=20, and as there are 37 fruits now 37-20=17 oranges must be removed.

The objective here is that 70% of the fruit in the box should be apples.

Now, there are 14 apples at start and there is no talk of removing any apples, so number of apples should remain 14 and they should constitute 70% of total fruit, so total fruit = 14/0.7 = 20

So we should have 20-14 = 6 oranges.

Right now, there are 23 oranges, so to get to 6 oranges, we should remove 23 - 6 = 17 oranges.

The content of a certain box consists of 14 apples and 23 oranges. How many oranges must be removed from the box so that 70 percent of the pieces of fruit in the box will be apples?

A. 3 B. 6 C. 14 D. 17 E. 20

x= orange to be removed 14=70%(37-x) x= 17

A. 3 B. 6 C. 14 D. 17 E. 20

Testing ans choices If D = 17 no of oranges to be removed means there are 6 oranges left and 14 apples left a total of 20 fruits. 14 = 70% of 20 therefore D Is the correct ans
