Answer:
(i) Factors of 35 are 5 and 7 and we know that, a number is a multiple of each of its factor. Hence, 35 is a multiple of 7. (ii) We know that, a factor of a number is an exact divisor of that number. Here, 30 is divided by 15. So, 15 is a factor of 30. (iii) Factors of 16 are 2 and 8 and we know that, a number is a multiple of each of its factor. Hence, 16 is a multiple of 8. (iv) We know that, every number is a factor of itself. So, 20 is a factor of itself i.e. 20. (v) We know that, a factor of a number is an exact divisor of that number. Here, 50 is divided by 25. So, 25 is a factor of 50. Now, matching of these items is as follows: (i) \[\to \] (b) (ii) \[\to \] (d) (iii) \[\to \] (a) (iv) \[\to \] (f) (v)\[\to \] (e)
