We can't talk about syllabus over here but it's wrong only Saathvik and Shaurya I think you did not read that multiples are equal to or greater than the number itself. And FACTOR are smaller than or equal to the number.

Ans 41:

Class : Class 9
MULTIPLES ARE NOT LESS THAN THE NUMBER,THE ANSWER IS GIVEN WRONG

Ans 42:

Class : Class 7
Answer should be B. Only negative numbers when multiplied by a positive number is a smaller number. Negative numbers are out of syllabus for 4th grader. Hence the given solution is wrong.
