A song stored on a CD is, on average, 4 megabytes in size. Amit wishes to transfer 4000 such songs onto a memory stick. Estimate the minimum size of the memory stick, in GB, that Amit will need to use.
A8 GB
B16 GB ✓ Correct
C32 GB
D24 GB
Correct answer: (B) 16 GB — The minimum size is 16 GB, so the answer is 16 GB.
Explanation
★The minimum size is 16 GB, so the answer is 16 GB.
★Each song is about 4 megabytes.
★So 4000 songs need 4 times 4000, which is 16000 megabytes.
★One gigabyte is about 1024 megabytes.
★So 16000 megabytes is a little under 16 gigabytes.
★The smallest standard stick that can hold this is 16 GB.
★So the minimum size is 16 GB.
