a contractor estimates that 16 men can renovate a house in 35 days. if he uses only 10 men, how long will they take to finish the same work?
Answers
6 men will do the work in 12 days
1 man will do in 6*12 = 72 days
So, 5 men will do it in 72/5 = 14.4 days
There are two types of relation
Direct relation - If one quantity increases then the other also increases and if one quantity decreases then the other also decreases.
Example- If 3 pencils cost Rs 7, then what will be the cost of 5 pencils ?
3 pencils cost Rs 7
1 pencil will cost Rs 7/3 (First divide)
5 pencils will cost Rs (7/3)*5 = Rs 11.66 (Then Multiply)
Inverse relation : If one quantity increases then the other decreases and if one quantity decreases then the other increases.
Example - This question itself is the example of inverse relation. Here first we did multiplication and then division.
I hope it clears the image….

Answer: 56 days
Step-by-step explanation:
Given,
i) 16 men can build house in 35 day
ii) 10 Men = ?
To find: We have to find time taken by 10 workers to do same work.
1 person can build house in No. Of days.
1 Person = 16 * 35
= 560 days.
So, If that contractor gives work to one person, then worker will complete it in 160 days.
And, As per as question, It is given that there are 10 men.
∴ 560/10 = 56
It means that 10 men require 56 days for building the house.
Therefore, 10 workers will do same work in 56 days.
Explanation:
In this question, First 16 men can do the work in 35 days and in second there was only no. of workers. So, we have to find the no. of days.
According to question, We multiplied 16 with 35 and we get 560. After that, we divide 560 with 10 workers. So, we get 56.
So, 56 days are require to do same work for 10 workers.
