Given: <u>The average mass of all the students in the class was 35.1 kg. After 1 student left the class, whose mass is 32.3kg, the average mass of the remaining students became 36.3kg, how many students were there in the class room now?</u>
Find out: <u>how many students were there in the class room after one student </u><u>left</u>
Solution: <u>Let the total number of remaining student be= n</u>
<u>Let the total number of remaining student be= nAnd the sum of mass of all the students be = x </u><u>kg</u>
So,

Make x the subject of formula

And





divide both side by n

N = 2.333
so total number of students remaining is 2
Answer:
b=16
Step-by-step explanation:
75%=75/100=3/4
3/4*b=12
b=12/1*4/3
b=16
The total is 256
12 x 5 =60
60x2=120
12x4=48
48x2=96
5x4=20
20x2=40
120+96+40=256
