Fun WIth Maths: Find the Missing Number in The Picture – Smiley Version

To solve this riddle let substitute the smileys with letters so that we can solve them;

Let;

Y = Yellow smiley;
G = Green smiley &
P = Pink smiley

Let’s rewrite the equations with these letters;

Y + G = 50 ——————(1)

Y + Y + Y = 120 ———–(2)

P + G = 35  ——————(3)

P = ?

From 2 we can write;

3Y = 120

Therefore;

Y = 40;

Putting value of Y in (1) we get;

40 + G = 50

Therefore G = 10;

Now in (3);

P + G = 35

substituting value of P we get;

P + 10 = 35

P = 25

Therefore the value of the missing number is 25
