Number Puzzle #175

find out the missing number

2 3 1 2

3 4 4 5

5 6 6 7

30 43 51 ?

2 6 18

4 20 100

X 21 147

Check your answer:-

in first row next number is a multiplication of 3 and the previous number

second row, next number is a multiplication of 5 and the previous number

in third row 3rd number (147) is a multiplication of 7 and previous number, i.e. 21, thus X*7 = 21 =>

If 10-2= 33

37-23=83

82-4= 43

55-7=32

then 76-45=?

Answer With Explanation

3.5 | + | 4.5 | = | 8 |

+ | + | |||

9.5 | – | 3.5 | = | 6 |

|| | || | |||

13 | 8 |

**Explanation**:

We can make four equations

A+B = 8

C-D = 6

A+C = 13

B+D = 8

now we have four variables with four equations so it should be easy to solve. let’s solve these four equations

if we add the four equations

A+B+C-D+A+C+B+D = 8 + 6 + 13 + 8

2(A+B) + 2C = 35

2C = 35 – 2*8 —- by replacing A+B

2C = 35 – 16 = 19

C = 9.5

from 2nd Equation C – D = 6

D = C – 6

D = 9.5 – 6

D = 3.5

from 3rd equation

A+C = 13

A = 13 – C

A = 13 – 9.5

A = 3.5

from 4th equation

B + D = 8

B = 8 – D

B = 8 – 3.5

B = 4.5

If February=June,

January=April,

September=September,

and August=April…

then **what is March?**

IF,

9 = 100,

8 = 143,

7 = 162,

6 = 165,

Then,

5 = ?

- 1
- 2
- 3
