Persistent Mathematical Orders Quiz 1

According to question statement, calculations can be done as:
= 664 + 56 - 50 + 30
= 720 -50 + 30
= 700

According to question,
56 will be replaced by 67
86 will be replaced by 97
72 will be replaced by 83
65 will be replaced by 76
Hence expression will be replaced by:
= 67 + 97 - 83 - 76
= 5

7 will be written as ….
Hence 17 represents …..

On interchanging / and +, we get the equation as
\frac{18}{2} * 2+5 - 1 = 22
22 = 22, which is true.

Replacing symbols the result will be:
= 47 + 3 -( \frac{4}{4} )* 5
= 45

Now, change the alphabet into the signs,
= 117 ÷ 3 - 5 + 12 * 8
= (\frac{117}{3}) -5 + 12 * 8
= 39 - 5 + 96
= 135 - 5
= 130

Given, 3 - 5 + 8 = 0
On interchanging signs '+' and '-' and number 3 and 5 in option (a), we get
5 + 3 - 8 = 0
8-8 = 0
0 = 0, which is true

Given, 7 * 5 + 3 = 26
On interchanging signs '+' and 'x' and number 7 and 5 in option (2), we get
5 + 7 * 3 = 5 + 21= 26

Here the equation is : \frac{0.095}{x} = 0.05
So, x = \frac{0.095}{0.05}
Hence, x = 1.9

From option 1, 28 ÷ 7 + 12 - 16 = 0
LHS =\frac{28}{7} + 12 - 16
= 4 + 12 - 16 = 16 -16 = 0
