c) 8047.228 d) 8012.422
Sol: We can add the all digits of the number and multiply.
Then we can get the resultant number. The resultant number also we can add the all digits to convert a single digit.
Which option will satisfy the digit sum of the question that option should be the answer.
12.9 × 14.6 × 42.7 = x
3 × 2 × 4 = x
24 = x 
6 = x
Option ‘a’ digit sum is also 6 so the option ‘a’ is the solution.
Ans: a
