Question

Your MP3 player has 32 gigabytes of music on it. During the next sync, you add 25% more music to it, and it is full. How many gigabytes does the MP3 player hold now?

Answer 1

42.6667 gigabytes (rounded up to four decimal places).

Explanation:

The MP3 player currently has 32 gigabytes

You add 25% more music and its full

When its full its 100% music

So it currently has 100% - 25% = 75% music

75% music is equal to 32 gigabytes

How many gigabytes are in 100%?

Cross multiplying gives:

(100 × 32) ÷ 75 = 42.6667 gigabytes (rounded up to four decimal places)
