Multiples of 9 from 1-300; \(\frac{300}{9} = 33.33\) i.e. 33 numbers
Since, we are looking numbers from 10 - 300, subtract 1 from it = 32 numbers
Col. A: 32
Col. B: 32
Hence, option C

Using the range formula:
(Max multiple within range - Min multiple within range)/(Spacing) +1
(297-18)/9 +1
32, Option C
(Max multiple within range - Min multiple within range)/(Spacing) +1
(297-18)/9 +1
32, Option C
