Four children Pallavi, Shilpa, Lisa and Akhila were each asked to choose a number between -15 and 15. The numbers chosen were -13, -4,9 and 13. The number that Pallavi chose was equal to the difference between Shilpa's number and Akhila's number. Lisa's number was smaller than Pallavi's number. What was Lisa's number?

Answer 1

Explanation:

We know that Pallavi’s number is equal to the difference between Shilpa’s number and Akhila’s number. Therefore:

Pallavi’s number = Shilpa’s number - Akhila’s number

Substituting the given values:

-13 = -4 - 13

Simplifying:

-13 = -17

This is not true, so we made a mistake somewhere. Let’s try again.

We know that Lisa’s number is smaller than Pallavi’s number. Therefore:

Lisa’s number < Pallavi’s number

Substituting the given values:

Lisa’s number < -13

We don’t know Lisa’s exact number, but we do know that it is smaller than -13. Therefore, we cannot determine Lisa’s exact number from the given information.
