You can write the equations by substituting;

Basketball by BB,

Football by FB &

Volleyball by VB.

So the equations would become;

  1. BB – BB – BB = -10
  2. BB – FB = -20
  3. FB – VB = 10
  4. VB – FB + BB = ?

Solving the first equation we get;

BB – BB – BB = -10

BB = 10

Putting this value in the second equation we get;

BB – FB = -20

10 – FB = -20

Therefore;

FB = 30

Putting this value in third equation we get;

FB – VB = 10

30 – VB = 10

Therefore;

VB = 30 – 10 = 20

Putting all the values in the fourth equation we can find the value of the missing number as;

VB – FB + BB = ?

20 – 30 + 10 = 0

Answer = 0

  1. the 2nd statement is unnecessary, you don’t need to know the value of the Football or Volleyball
    1st statement gives 0 – Basketball = -10
    Basketball = 10
    ignore 2nd statement
    add 3rd statement to 4th statement > gives
    Football – Volleyball + Volleyball – Football + Basketball = 10 + ?
    reduce to Basketball = 10 + ?, thus ? must be Zero
