There are 3 types of fruits in a basket; mangoes, apples and oranges. The number of apples is 60 less than two times the remaining fruits. Three times the number of mangoes is 30 more than the remaining two put together. If three times the number of oranges is 30 more than the number of mangoes, how many apples are there in the basket?

1) 20
2) 30
3) 40
4) CBD

• a = 2 (n + o) - 60 => 2m + 2o - a = 60
  3m = 30 + (o + a) => 3m - a - o = 30
  3o = m + 30 => (30 - m ) = 30
  
  These have infinite solutions
  Possible value among the given = a = 40
  
  Hence it cannot be determined.
