Explanation:
20 men can do 1 W in 36 days
=> 20 men can do 1/36 W in 1 day
=> 10 men can do 1/72 W in 1 day.
30 girls can do 1W in 36 days
=> 30 girls can do 1/36 W in 1 day
=> 12 girls can do 1/90 W in 1 day.
Together 10 men and 12 girls can do 1/72 + 1/90 W in 1 day
= 9/360 = 1/40 W in 1 day.
Therefore they need 40 days to do the piece of work.
Answer: a. When prices in the stock market are up nothing happens. If they are down, the economy is in trouble.
Explanation:
The beauty of the economy is when the stock market is up. It means there would be more money in circulation to do businesses and when businesses are done the economy is wealthy and everyone is affected positively to a great extent. When there is a crash in the stock market it demoralizes the economic growth and lower stock price would mean a reduction in money used in businesses as companies won't want to commit much funds to doing business.
