• A. Seven hundred seventy-seven
• B. Seven hundred
• C. Seven hundred seventy
• D. Seven hundred seven

Answer 1

The correct option is D Seven hundred seven

Number of seats in each row $=10$
Number of rows occupied by adults $=40$
Total number of seats occupied by adults $=40$ Tens $=4$ Hundreds $=400$
Number of rows occupied by kids $=30$
Total number of row seats occupied by kids $=30$ Tens $=3$ Hundreds $=300$
Number of extra seats occupied by kids $=7$
So, total number of seats occupied by kids $=300+7=307$
Total number of occupied seats $=400+307=707$
$\begin{array}{cccc}& \text{H}& \text{T}& \text{O}\\ & 4& 0& 0\\ +& 3& 0& 7\\ & 7& 0& 7\end{array}$
The number name of $707$ is ‘seven hundred seven’.
Hence, seven hundred seven seats are occupied in the stadium.
