In the picture below you will see burger, pizza and cola representing certain numbers.
Find the value of each and then find the value of the missing number.
To solve the riddle we first substitute the pictures with letters;
Let’s assume the following;
Burger = B
Pizza slice = P
Cola drink glass = C
We can rewrite the equations as;
B + B + B = 30 ————- (1)
B + P + P = 20 ————- (2)
P + 2C + 2C = 9 ————- (3)
&
P + C x B = ? ————- (4)
From (1)
3B = 30
Therefore;
B = 10
From (2)
B + 2P = 20
10 + 2P = 20
2P = 10
Therefore;
P = 5
From (3)
P + 2C + 2C = 9
5 + 4C = 9
4C = 4
Therefore;
C = 1
To find the missing number in (4)
P + C x B = ?
Substituting the values of B, P & C in (4) we get;
5 + 1 x 10 = 5 + 10 = 15
Answer = 15
