Question

10 women can complete a work in 7 days and 10 children take 14 days to complete the work.How many days will 5 women and 10 children take to complete the work?

Given

• 10 women can complete a work in 7 days.
• 10 children take 14 days to complete the work.

Find

• How may days will 5 women and 10 children take to complete the work ?

Solution

• Let women be x
• children= y

→ 10x × 7= 10y × 14

→ x : 2 y

$\sf → \frac{x}{y}=2/1—eq(i)$

$\sf→ 10 x×7=(5x×10y)z$

• ★ Let z be the number of days required

So from eq(i)

→ $\sf 10×2×7= (5×2+10×1)z$

→ $\sf 140=20z$

→ $\sf z = \dfrac{\cancel{140}}{\cancel{20}}$

→ $\sf z =7 days$

Hence

• Number of days required = 7
