P=l+b×2 L=5w B=w =5w+w×2 =6w×2 =12w cm

## Ans 2:

Class : Class 7
Breadth=w, Length is 5 times more, Therefore, length = 5w Therefore, perimeter=2(5w+w) =2*6w =12w Hence, b is the correct answer

There is a problem in this question. Please correct this.

Class : Class 6
its wrong!!!

## Ans 3:

Class : Class 7
Then the calculation will turn to 20 +8/4x3x2, =20+2x3x2, =20+6x2, =20+12 =32, so there is a problem in the question

## Ans 5:

Class : Class 7
The divisions sign is used in 2 places, but I think it means subtraction because '-' meaning subtraction is not exactly coding anything...And in that case 20 8/4-3x2=20 2-6=16...Which is not an options for whatever weird reason

## Ans 6:

Class : Class 4
yes there is an error in the question

Class : Class 7

## Ans 8:

Class : Class 6
How can you change 2 to 3? and how can you mark division symbol as addition and subtraction? SOF DON'T DO SUCH MISTAKES OR WE'LL HAVE TO REPORT IT TO sofworld.org

## Ans 9:

Class : Class 9
yes there is a problem in the question

## Ans 10:

Class : Class 6
answer should be 16 as - coded for subtraction doesn't really code anything so it is 22-6=16

## Ans 11:

Class : Class 6
Ya there is a problem...............answer is 32 you seee

## Ans 12:

Class : Class 6
There is problem in the Q as it mentions division sign represents both addition and substraction

In ΔAED
AE D + ∠EAD + 90° = 180° (Angle sum property)
⇒ ∠AED + ∠EAD = 90°
⇒ ∠EAD = 90° – ∠AED ...(i)
Also, ∠EAD = (50° + ∠AFB) ...(ii) (Exterior angle property)
From (i) and (ii), we have
50° + ∠AFB = 90° – ∠AED
⇒ ∠AFB + ∠AED = 90° – 50° = 40°
⇒ ∠AED + ∠CFD = 40°

In the 1st column, 2 X 1 + 1 = 3,

In the 2nd column, 12 X 9 + 9 = 117

Similarly, In the 3rd column, 7 X 14 + 7 = 105

Hence, the missing number is 7.
