A. 60
B.40
C.30
D. 10​

Answer 1

Given that:

In a magic square,

• The sum of every row, column and diagonal is the same.
• Row 1: x, x + 5, 8
• Row 2: x + 1, y, y - 2
• Row 3: 2, 9, 4

To Find:

• What is the value of 10x?

According to the question.

Row 1 = Row 3

↠ x + x + 5 + 8 = 2 + 9 + 4

↠ 2x + 13 = 15

↠ 2x = 15 - 13

↠ 2x = 2

Multiplying 5 both sides.

↠ 2x × 5 = 2 × 5

↠ 10x = 10

Hence,

• The value of 10x is D. 10.

Answer 2

Step-by-step explanation:

given :

magic square 1 = x, x + 5, 8

magic square 2 = x + 1, y, y - 2

magic square 3 = 3: 2, 9, 4

to find :

value of 10x = ?

value of 10x = ?

solution :

magic square 1 = magic square 3

• magic square = x + x + 5+8=2+9+4

• magic square = 2x+13= 15

• magic square = 2x = 15 - 13

• magic square = 2x = 2

multiply with 5

• magic = 2x5 = 2 x 5

• magic = 10x = 10

hence , the value of magic square = 10
