Find missing number in math puzzle

Question: Find missing number in math puzzle:

Answer: Let M = Mario

Z = Zelda

Mi = Mickey Mouse

Equation 1:

M + M + M = 60

3M = 60

M = 20

Equation 2:

M + Z + Z = 30

M + 2Z = 30

2Z = 30 – M

2Z = 30 – 20

Z = 5

Equation 3:

Z + Mi + Mi = 9

Z + 2Mi = 9

2Mi = 9 – Z

2Mi = 9 – 5

2Mi = 4

Mi = 2

Equation 4:

M + Z x Mi = ?

= 20 + 5 x 2

= 30

Answer = 30

Question: Find the missing number in this riddle:

The number in the center is the multiplication of numbers on both sides such as 12 (in the center) is equal to multiplication of 4 & 3 (numbers on both sides).

Hence we can conclude that the missing number (in the center) is equal to the multiplication of numbers 3 & 5 (on both sides). Hence missing number is equal to 15

Answer = 15

Question: Find the value of Chicken in math question:

We replace chick with C, & solve to get its value.

C / (C+2) = 4 / 5

5C = 4 x (C + 2)

5C = 4C + 8

5C – 4C = 8

C = 8

Hence Chick = 8

Solve tricky math problem using PEMDAS – cat version:

• 2 shoe + 2 shoe + 2 shoe = 30  ---- (1)
• 2 shoe + (cat + whistle) + (cat + whistle) = 20  ---- (2)
• (Cat + whistle) + 2 whistle + 2 whistle = 13  ---- (3)
• 2 shoe + cat x whistle = ?  ---- (4)

Tricky part of this problem is that cat is wearing a whistle in equations 2 & 3 but it has no whistle in equation 4.

Solving first equation:

6 shoe = 30

Shoe = 30 / 6

Shoe = 5

Solving second equation:

2 shoe + (cat + whistle) + (cat + whistle) = 20

Using value of shoe, we get:

2 (5) + 2 (cat + whistle) = 20

10 + 2 (cat + whistle) = 20

2 (cat + whistle) = 10

Cat + whistle = 5 ---- (5)

Solving third equation:

(Cat + whistle) + 4 whistle = 13

Using value of cat, we get:

5 + 4whistle = 13

4Whistle = 13 - 5

4Whistle = 8

Whistle = 2

Equation 5:

Cat + whistle = 5

Using value of whistle, we get:

Cat + 2 = 5

Cat = 3

Now solving the final equation:

2 shoe + cat x whistle = Unknown

Using values of shoe, cat & whistle, we get:

2 (5) + 3 x 2 = Unknown

Multiplication must be solved before addition, based on PEMDAS rule:

10 + 6 = Unknown

16 = Unknown

Answer = 16

Find missing number in math puzzle - cars version:

We have 3 cars: Blue Car, Green Car & Red Car

First equation:

Blue Car + Blue Car + Blue Car = 18

3 Blue Car = 18

Blue Car = 18 / 3

Blue Car = 6

Second equation:

Red Car + Red Car + Red Car = 9

3 Red Car = 9

Red Car = 9 / 3

Red Car = 3

Third equation:

Green Car x Green Car – Green Car = 6

Green Car^2 – Green Car = 6

Use Green Car = 3 & solve above equation:

3^2 – 3 = 6

9 – 3 = 6

6 = 6

It satisfies above equation so Green Car = 3

Last equation:

Blue Car x Red Car – Green Car = ?

Use values of Blue Car, Red Car & Green Car in above equation:

= 6 x 3 – 3

= 18 – 3

= 15

Answer = 15
