A group of 10 men can complete a project in 30 days. Just as they are about to start working on the project, 2 men are replaced by 2 women. On the second day, 2 more men are replaced by 2 more women. This process goes on till 5 days, and all the men are replaced by women. If the entire work gets completed in a total of 45 days, find the ratio of work done by one man in one day to work done by one woman in one day.
is this way correct to do the question? if yes then why my ratio is coming out to be 43:24 and not 43:28? have I done some calculation mistake?

A machine installed in a factory manufactures plastic bottles in batches. As the machine has worn out, the longer the machine works, its operating costs keeps on increasing. For example, the cost of manufacturing 200th bottle in a batch is costlier than manufacturing the 1st bottle. The cost of manufacturing each bottle in a batch depends upon the position at which the bottle is manufactured.
The following line graph gives us the cost per manufacturing a bottle based on the position at which the bottle is being manufactured.
For example in the graph given above, to manufacture the 50th bottle, it costs Rs. 25 while to manufactore the 100th bottle, it costs Rs. 30. Similarly, the manufacturing cost of each bottle remains constant at Rs. 30 from the 100th to the 200th bottle but again start increasing after the 200th bottle is manufactured.
A batch is defined as the total number of bottles being manufactured at a time by the machine. The cost per bottle is reset every time a new batch starts
If the manufacturer gets an order of 600 bottles, what is the cost per bottle in the cheapest possible way ? Due to time constraints, maximum of 2 batches are possible. Assume that any batch size has to be a multiple of 50.
Why have we not considered the 600 bottles being split as
(50,450) and (100,500) batches ?

The number A39K2 is completely divisible by both 8 and 11. Here both A and K are single digit natural numbers.
Which of the following is a possible value of A+K?
In the video solution it is given, A-K+8 = 11X, Could you please explain from where this 11X came and why we are putting 0 and 1 in the place of 1. Please tell me if it is a mathematics rule so I can understand it from the basic or May be I am misreading something. ?
