Question

if 20 men can complete a piece of work in 18 days in how many days can 24 men complete the same piece of work​

Answer 1

Step-by-step explanation:

• 20- men can do a work in = 18 days
• In 1- day 1- man can do= 1/360 work
• 20 men in 3-days can do=(20x3)/360 =1/6 work.
• The remaining 5/6 work will be done by (20+10)= 30- men in= 5/6÷(30/360)
• = (5/6)x (12/1)= 10- days.
• So in 10- more days the remaining (5/6) - work will be completed.

Answer 2

$\mathfrak{ \large{ \purple{ \underline{ \underline{solution}}}}} \\ \\ \small \implies \: 20 \times 18 = 24 \times x \\ \\ \small \implies \: 360 \: = \: 24x \: \: \: \: \: \: \: \: \: \: \: \\ \\ \: \small \implies \: \frac{360}{24} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \small \implies \: 15 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$
