CBSE NET JANUARY 2017 PAPER II
How many multiples of 6 are there between the following pairs of numbers?
0 to 100 and
-6 to 34
(1) 16 and 6
(2) 17 and 6
(3) 17 and 7
(4) 16 and 7
Ans: (3)
Explanation:
This question can be solved using simple logic too.
Number of multiples of 6 between 1 to 100 = 100/6 = 16
Since the range starts from zero, we need to take zero too.
Note: zero is a multiple of every integer,except zero itself.
So, answer = 16+1 = 17
Number of multiples of 6 between 1 to 34 = 34/6 = 5
Since the range is -6 to 34, we need to take -6 and zero.
So, answer = 5+2 = 7
So option 3 is correct.
