please give the correct answer correctly for class 8 ​

Answer 1

Answer:

Yes

Step-by-step explanation:

The persons involved in a work and time taken is inversely proportion. Because of 'Work done'. Here there are three things. The person, Time taken and the- invisible one is- Work done. More quantity of work done takes lesser time. For example you are going to packing of books into boxes. It will take 1 hour. If your friend also join with you in that same work, what will happen? The time taken should be less than the previous case (1/2 hour). So, what is happening here ? More amount of work done takes less time. You and your friend's work done combine here and forms more efficiency.
