If 2 men or 3 women can do a piece of work in 30 days, in how many days can the work be done by 2 men and 6 women?

Solution
2 men's 1 day's work =\(\frac{1}{30}\)
3 women's 1 day's work=\(\frac{1}{30}\)
∴ 6 women's 1 day's work=\(\frac{1}{15}\)
(2 men + 6 women)'s 1 day's work =\(\frac{1}{30}+\frac{1}{15}=\frac{1}{10}\)
The work can be done in 10 days
If the average of 5 consecutive numbers is 23, find the smallest number

Solution
Suppose the numbers are x, x + 1, x + 2, x + 3, x + 4
\(23=\frac{x+(x+1)+(x+2)+(x+3)+(x+4)}{5}\)
⇒ 115 = 5x + 10
⇒ 5x = 105
⇒ = 21
