Solution

The correct option is A
$366329$

Find the value of given expression
Given that, $3 + 5 + 6 = 151872$
$(3 \times 5) = 15$
$(3 \times 6) = 18 .$
$(15 + 18) - 6 = 33 - 6 = 27$
Write the number $27$ in the reverse order and number obtained is $72$
So, $3 + 5 + 6 = 151872$
Similarly, $9 + 4 + 7 = 366329$
$(9 \times 4) = 36 (9 \times 7) = 63$
$(36 + 63) - 7 = 92$
Now, write the number $92$ in reverse order and the number obtained is $29$
So $9 + 4 + 7$ $= 366329$
Hence, option (A) is correct.
