Answer 1

Solution :-

Day --------------------------- Number of students present

Monday ------------------------------------- 42

Tuesday ------------------------------------- 36

Wednesday -------------------------------- 40

Thursday ------------------------------------ 36

Friday --------------------------------------- 38

given that,

→ Total students in class are = 42 .

so,

→ All students present in school are = On Monday .

now,

→ Students present on Friday = 38

then,

→ Students absent on Friday = 42 - 38 = 4

therefore,

→ % of students absent on Friday = (4 * 100)/42 = (200/21) = 9(11/21) % (Ans.)
