C is the answer to this question but it is showing that D is the answer. Master answer required

Class : Class 6
128 sq cm

## Ans 11:

Class : Class 5
In the question it is written 2m for knots, which means 122m of rope is required. If it would be given 2m for each knot then the answer is 128m.

## Ans 12:

Class : Class 5
option d according to SOF but it should be option c as it has said for the knots. The word ''knots'' is in plural form which means there are many knots which means it will be a l the knots counted

## Ans 13:

Class : Class 8
Answer is D, because 2m for EACH knot, so multiplying by 4 gives 8. Then adding to 120 gives answer 128. As this answer is not in options A, B and C, answer is D, none of these

## Ans 14:

Class : Class 5
Answer: 128Explanation:Perimeter = 30 x 4 = 120Space for knots = 2 x 4 = 8 (each knot = 2m)Total (answer) = 30 x 4 2 x 4 = 128 m 128 > 120, 118 or 122 so option D. None of these is the correct option

## Ans 15:

Class : Class 7
Answer should be Option C, not D, because 2 meter for knots is mentioned. It is not mentioned that 2 m is required for each knot.

Class : Class 8
None of these

Class : Class 6

## Ans 18:

Class : Class 5
Answer is C: 122. It says 2m is required for tying the "knots" which means 2m is the total length consumed the all knots. Had it said that 2m is required for each knot then the answer would be 128m.

## Ans 19:
