Correct Answer: (1)
Solution: (1) $\because 28$ men do 1 work in 15 days.
$\therefore$ Time taken by 30 men $=\frac{15 \times 28}{30}=14$ days
$\because \quad 15$ women do the work in 24 days.
$\therefore$ Time taken by 18 women $=\frac{15 \times 24}{18}=20$ days
$\therefore \quad$ Required ratio $=\frac{1}{14}: \frac{1}{20}$ $=20: 14=10: 7$
