Answer 1

$\large\bf\underline{\green{\mathbb{C} orrect \:\mathscr{Q}uestion...}}$

• 12 ,10, (34) ,7, 8
• 32 , 23 ,(?) ,9, 7
• 34 ,43 (13) ,10 ,9

$\bf\underline \blue {To \: \mathscr{f}ind:-}$

• we need to find the hidden digit .

$\huge\bf\underline \red{ \mathcal{S}olution...}$

Logic is that we need to subtract the sum of First two numbers from the product of last two numbers .

• a = first number
• b = Second number
• c = bracket number
• d = 4th number
• e = 5th number

Logic :-

• ( d × e ) -( a + b ) = c

1) 12 ,10, (34) ,7, 8

↛c = 7 × 8 - (12 + 10)

↛c = 56 - 22

↛c = 34

2) 34 ,43 (13) ,10 ,9

↛c = 10 × 9 - (34 + 43 )

↛c = 90 - 77

↛c = 13

3) 32 , 23 ,(?) ,9, 7

• By using the same logic

↛ c = 9 × 7 - (32 + 23)

↛ c = 63 - 55

↛ c = 8

So,

• The Missing number is 8

Answer 2

Answer:

Explanation:

Hey friend......

Perimeter = circumference

Here diameter of the mat is given,

Radius=84/2=42

Cifcumferance=

Therefore

= 22/7× 42

=132cm
