Correct Answer: 10.125

Solution : Given:
81, 243, 40.5, 121.5, 20.25, 60.75, ?

In the above-given series, multiply by 3 and divide by 6 alternatively the previous number to get the next number.
81 × 3 = 243, 243 ÷ 6 = 40.5, 40.5 × 3 = 121.5, 121.5 ÷ 6 = 20.25, 20.25 × 3 = 60.75, 60.75 ÷ 6 = 10.125

So, 10.125 is the missing number of the series. Hence, the third option is correct.
