If 5 workers complete one task in 7 days, then how many days will 7 workers take to complete the same task?
5 men take 7 daysSo 1 man will take (7*5) = 35 days. ( Its obvious that 1 man will take more days so simply multiply to get days taken by 1 man)Now, 7 men will take 35/7 = 5 days. ( Its again obvious that when we increase the number of people then the work will be done faster in less days and so we divided)This is a case of inverse proportionality where a decrease in one quantity leads to increase in other quantity and the increase in oje quantity leads to decrease in the other. As you can see that if number of men increases then days decrease and if men decrease so days increase. Whenever you see such case, simply follow the rule…First multiply then divide.I hope it was clear enough.

Learning how to draw at 19 years old?
I'm a big fan of comics as well as various artistic expressions that all start with pencil drawing skills, and even though I really want to make some art myself, I feel that I may be a little too late because of my age and since I've never seen to have a natural skill in any artistic expression.
The scale on a drawing is 1 mm = 3 m. How many meters does 2 centimeters represent?
2 cm = 20 mm * 3 = 60 m
20 workers can finish a work in 30 days. After how many days should 5 workers leave the job so the work is completed in 35 days?
First of all we convert it in unit like this20 workers × 30 days = 600 units workAfter leave the 5 workers , we have 35 days for complete the work.In 35 days only 15 workers will do the work.So the work completed in 35 days by 15 workers = 35 ×15 =525 unitsRemaining unit = 600 -525 =75 unitsThis units would done by 5 workers in ( 75/5) = 15 days .So after 15 days 5 workers should leave the job.
