          Answer the following questions on the basis of the above data.
              1.  What is the minimum number of trees you will acquire for planting trees, so that they can
                  be distributed equally among all students?
                  (i)  480                (ii)  22                 (iii)  2                 (iv)  455
              2.  Find the HCF of (32, 30), using the relationship between HCF and LCM of two numbers.

                  (i)  1                  (ii)  2                  (iii)  3                 (iv)  4

              4.  1 × 2 × 3 × 7 × 9 + 2 is a:

                  (i)  composite number                            (ii)  prime number
