pls answer fast ​

Answer 1

Answer:

Let us take Karan's marks as some x.

Then Bhavana's marks are (x- 10).

Isha's marks are (x-10 -10) = (x- 20)

Now we have the total marks of the three as 140.

Therefore x + x - 10 + x - 20 = 140

          Or  3x - 30 = 140

           Or  3x = 170

           Or x= 170/3

          Or x = 56.6

Therefore Karan has got 56.6 marks.

Let's verify.

If Karan has 56.6 marks, Bhavana will have 46.6 marks and Isha will have 36.6 marks. The total is nearly 140 so our answer is right.
