Please help me!!!!!!Thanks a lot Answer by Jstrasner(112) (Show Source):
You can put this solution on YOUR website! Hey,
For this problem we need to figure out what an average score of 74 is in terms of 4 numbers.
To do this, we need to multiply 74 by 4: 74 x 4 = 296.
To find that fourth number, we need to ass the other three numbers and subtract their sum by 296:
60 + 69 + 75 = 204 => 296 - 204 = 92. That is the score that nandan must get.
I hope this helps!
