None of these

- Let's examine the given number series: 60, ?, 63.6, 70.8, 99.6, 243.6.

- The pattern in the series looks like a sequence of increasing numbers.

- Check the differences between consecutive numbers:

- 63.6 - ? = 3.6

- 70.8 - 63.6 = 7.2

- 99.6 - 70.8 = 28.8

- 243.6 - 99.6 = 144

- Notice that these differences (3.6, 7.2, 28.8, 144) are multiples of 1.2 increasing by multiplying by 2, 4, and 5 respectively.

- Hence, the pattern suggests 60 + 1.2 = 61.2.

- Correct Answer: Option 2 - 61.2
