Answer is B

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

Ans 3:

Class : Class 6
answer is 12W cm as the formula is 2*(length+breadth)=perimeter ,so w ( breadth) +5w (length) =6w (length+breadth) and then 6w *2 =12w(answer)

Ans 4:

Class : Class 7
P=l+b×2 L=5w B=w =5w+w×2 =6w×2 =12w cm

Ans 5:

Class : Class 7
6w

Ans 11:

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

Ans 12:

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

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

Ans 18:

Class : Class 7
ANSWER IS 16!!!

Ans 19:

Class : Class 8
the division sign represents both addition and subtraction and we can get to different answers

Ans 20:

Class : Class 6
yes pls correct the problem...

Ans 21:

Class : Class 8

Ans 22:

Class : Class 6
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 23:

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

Ans 24:

Class : Class 6

C

Ans 2: (Master Answer)

Class : Class 1

The correct answer is C.

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°
