1 One-fourth of the length of a rope is 10 meters
2 The total length of the three ropes is 120 meters
Only statement 1 is sufficient
Only statement 2 is sufficient
Either statement 1 or statement 2 is sufficient
Data insufficient​

Answer 1

Answer:

1. one fourth of the length of a rope is 10 metres

Answer 2

Question :

Which of the following statements helps you to determine the total length of 20 ropes each of the same length.

• One-fourth of the length of a rope is 10 meters
• The total length of the three ropes is 120 meters
• Only statement 1 is sufficient
• Only statement 2 is sufficient
• Either statement 1 or statement 2 is sufficient
• Data insufficient

Answer :

The last option is correct : Data insufficient

• In order to find out the total length of 20 ropes each of the same length, the length of at least one rope needs to be known.
• But here, no such data is provided except the number of rope and the fact that all the 20 ropes are of same length.

Suppose the length of a rope is x m.

If all the 20ropes are of same length then total length of 20 ropes will be = 20 × x

= 20x m

• Here again, to stand the value of total length , 'x'( length of a rope is needed) which is not provide.

Hence, Data is insufficient to find out the total length of 20 ropes.
