Step-by-step explanation:

subtract 12 from 512

the ans is 500,now think how many 4(1 song avg)is 500=125*4=500

Answer 2

Given,

Minni has a mobile, on which she downloads songs. The average size of each song is 4MB.

To Find,

The number of songs on minii's mobile.

Solution,

As it is stated, the average size of a song = $4$ MB

Thus in order to have songs of a total size of 512MB, the number of songs should be = $\frac{512}{4} = 128$ songs.

And since she is yet to download 3 more songs to have songs of a total size of 512MB, that means, she already has $128-3=125$ songs on her mobile.

Henceforth, the number of songs on minii mobile initially is 125.
