Answer:

40% of the student is 160

30% of the students is 120

10% of the students is 40

the remain is ___

160 + 120 + 40= 320

400 -320 = 80

meaning 160 students passes only math (40%). 120 students passed on science (30%). 40 students fail both subjects (10%) and 80 students passes both subjects (20%)
