During medical checkup in a Sharda World School, Sahiba who is a medical officer noted that the average height of 50 students in a class is 165cm. On a particular day, three students P,Q and R are absent, so the average of the remaining students becomes 163cm.

Explanation :
sum of height (50) = 50*165 = 8250
sum of height (47) = 47*163 = 7661
sum of the height of P, Q and R = 8250-7661 = 589
P+P+P-2 = 589 (as height of P is equal to Q and height of R = P -2)
P = 197

Let, the expenditure of ninth person = $X. Total expenditure of 8 persons = 8 × 30 =$ 240

According to the question,
$X - \frac{X+240}{9} = 20$
9X – X – 240 = 180
8X = 180 + 240 = 420
X=\frac{420}{8} = 52.5[/latex]
= $52.5 Now, Total expenses =$ 240 + $52.5 =$ 292.5

$290$ 290
