Let us assume the number of hours volunteered by Katie = x
Number of hours volunteered by Elizabeth = y
Number of hours volunteered by Siobhan = z
After one week,
x = y + 3
z = y - 1
After 3 weeks
3x = 3 (y + z)
Dividing both sides by 3, we get
x = y + z
Putting the value of x from the first equation in the third equation, we get
x = y + z
y + 3 = y + z
z = 3
Now putting the value of z in the second equation, we get
z = y - 1
3 = y - 1
y = 4
Putting the value of y in the first equation, we get
x = y + 3
= 4 + 3
= 7
The number of hours volunteered by Katie = 7 hours
Number of hours volunteered by Elizabeth = 4 hours
Number of hours volunteered by Siobhan = 3 hours
10,000 is 8.33% of 120,000.
10,000 / 120,000 = 0.0833 * 100% = 8.33%
Assuming that the whole and percentage is given. find the value of the percentage.
120000 * 8.33% = 9996 ⇒ 10,000
If the percentage is given and its corresponding value. find the whole
10,000 / 8.33% = 120,048 ⇒ 120,000
