Solve tricky math problem

Question: Find the missing number in logic math puzzle:

Answer: This is a logic math puzzle

16 = 62

Pattern: Reverse order of numbers in 16 to get 61.

Then add 1 to get 62 which is equal to Right Hand Side

Do the same in equation 2:

55 = 55 + 1 (Reversing order & adding 1)

= 56 = Right Hand Side

Equation 3:

28 = 82 + 1 (Reversing order & adding 1)

= 82 = Right Hand Side

Question: Solve tricky math problem:

It is a bit tricky math expression. We need to solve for the final expression & obtain result.

3 equations are given. There are 2 unknown variable star & ball. We can write equations from the above figure as:

Star + Ball = 9

Star – Ball = 3

Star x Ball = ?

The procedure follows as:

First obtain values of star & ball, & use it in the final equation & solve it.

We can solve for star in the second expression & put its value in the first expression to obtain value of ball.

Second Equation:

Star - Ball = 3

Star = Ball + 3

Now put value of star in the first equation:

Star + Ball = 9

Ball + 3 + Ball = 9

2 Ball = 9 – 3

2 Ball = 6

Ball = 3

Use value of Ball in the first expression to obtain value of Star

Star + Ball = 9

Star + 3 = 9

Star = 9 – 3

Star = 6

Now put values of Ball & Star in the third equation & solve the equation to obtain answer.

Star x Ball = ?

6 x 3 = 18

Hence multiplication of star & ball gives 18 which is the final answer.

Answer = 18
