There are 20 balls red,blue or green.if there are 7 balls are green and sum of blue and red balls are 1ess than 13.Then at most how many red balls are there?

• 7 balls are green and sum is less then 13
  so red balls can be atleast 1
  or atmost can be 5
  7 green & 5 red
  the sum will be then 13
  so 5 is the ans

• Is there a mistake in this question?? Bcoz it is given
  R+B+G = 20 -> eq1
  G=7(given) -> eq2
  B+R 1ess than 13 -> eq3
  Sub 2 in 1 we get, R+B=13 ( Here it is clear that sum of red and blue should be 13)
  In eq 3 it is said that the sum of Blue and red is less than 13 which means the sum of R&B should be 12...
