No. of days 1 2 3 4 5 6
No. of students 20 x 50 40 2x 60


The distribution above shows the number of days a group of 260 students were absents from school in a particular term. How many students were absent for at least four days in the term

A.

210

B.

40

C.

120

D.

160

Correct answer is D

20 + X + 50 + 40 + 2X + 60 = 260
3X + 170 = 260
3X = 260 - 170
3x = 90
x = 30
Absent for at least 4 days

4 5 6
40 2x 60


i.e 40 + 2x + 60 = 40 + (2 x 30) + 60
= 40 + 60 + 60
= 160
