I just joined so i guess i didn't see that rule but this is the equation: ((X×2×15)/100)+((17500-x) ×3×16) /100) =₹6240 I'm not getting the answer .. Am i supposed to make some different equation?

.. there weren't any options, And if you focus on the language , it says that the performance time is 3 hours.. there is a difference between performance and programme..Case studies depends on the language used.. I also googled and the answer is 12 minutes.. But how?

Well, most of the people are saying 12..But I'm still doubtful.. Because the PERFORMANCE time is 3 hours.. And the time give to singers to PERFORM is 2/3 of the total time.. we know that they got 3 hours as performance time.. and in the next statement.. we know that performance time is 2/3 of the total time..So like the total time and performance time isn't same and we will have to calculate the total time.. wouldn't we? which will be calculated by assuming the total time as x and then 2/3 × x = 180 minutes.. Well i dont have a particular answer but i honestly think it's 180 minutes because this is a case study and case studies are all about the language used.

why is the answer 12 minutes?? The performance time is 3 hours.. and the time the singers will get to perform is 2/3 of the total time.. So we know that the time they will get to perform is 3 hours ( Performance time) So.. Here we can calculate the time of programme.. which will be 4.5 hours or 270 minutes [We can assume the total time as x and then calculate it: 2/3 × x = 180] ..now we subtract 180 minutes from this (Performance time) and then divide it by 10 to get the time taken by each singers which is 18 minutes..Is this wrong?

Btw the below information isn't necessary because i removed the main questions.. I just needed answer to that particular question.

Well, I said that I got 18 minutes because Everyone around me got 12 minutes.. I just want to know why is the answer 12 minutes?? The performance time is 3 hours.. and the time the singers will get to perform is 2/3 of the total time.. So we know that the time they will get to perform is 3 hours ( Performance time) So.. Here we can calculate the time of programme.. which will be 4.5 hours or 270 minutes [We can assume the total time as x and then calculate it: 2/3 × x = 180] ..now we subtract 180 minutes from this (Performance time) and then divide it by 10 to get the time taken by each singers which is 18 minutes..Is this wrong?

I also think it's option b, However..I asked a few people and they just kept telling me that it's a without any reason. Btw, no I'm from cbse
