Mass Spectrometry

This process is an instrumental method in which a sample is changed to fast moving positive ions by electron bombardment. The charged particles vary due to their different mass to charge ratio and are estimated with the help of this difference. It is also called mass spectroscopy.

I am confused as to how to go about solving this problem. I already split them into three distinct hydrogens: the methyl group hydrogens, the hydrogens to the farther left of the NO2 group, and the hydrogens closest to the NO2 group. For the methyl group hydrogens, I expect 1 peak, for the ones farther to the left I expect n+1 = 2+1 = 3 peaks, but for the ones nearest the NO2 group, I believe they go through complex splitting and am confused. Detailed explanation would be appreciated.
