There was a mistake in the options. It has been corrected now.

Solution
Biggest 4 digit number formed from these digits = 8743
Smallest 4 digit number formed from these digits = 3478
Difference = 8743 - 3478 = 5265

Option A 84 m is the right answer. Solution : The area of square is 144 m as given. Hence, the side of square is 12 m. The length of one smaller square in the shaded square is 6 m. Hence the length of the rectangle is 6+6+6+6 =24 the breadth of rectangle is 6+6+6=18 The perimetre of rectangle is 2(l+b) = 2 (24+18) = 2*42 = 84 m

Ans is 84. Area of the square = 12 x 12 = 144 which means 12 is the length of two sides of the square, therefore each side will be 6 and there are 14 sides. Hence the perimeter is 14 x 6 = 84

## Ans 9:

Class : Class 6
I get 2.8 but the admin is not sure about the process and is saying the wrong answer-35 I need to know how did they get the solution

## Ans 10:

Class : Class 6
Why is the solution not clear.I am not understanding this solution. Always I have difficulty understanding these solutions.

## Ans 11:

Class : Class 5
THIS IS RIDICULOUS

## Ans 12:

Class : Class 7
yeah they are not clear in the solution. maybe the computer is programmed to show the specific lines of not being sure of the process
