<h3>Total snow fall for three days is 8.75 inches</h3>
<em><u>Solution:</u></em>
Given that,
Snow fell over the past three days

<em><u>What was the total snowfall for the three days?</u></em>
Total snowfall = first day + second day + third day

Thus total snow fall for three days is 8.75 inches
I don’t see any graph attached to the question
(i) the number of students who passed in the first and in the second division
76+95=171 students
(ii) The ratio of the number of students who passed in the first second and in the third division.
RATIO is 4:5:(25/19) or 4:5: 1.3157894…….
225-29=196 (29students failed)
196-25=171. (Subtract 25 students from the 3rd division)
4x+5x= 171 (171 students from 1st and second division)
9x=171
X=19
4x19=76 5x19= 95 1.31578.....x19= 25
