Solution

The correct option is B A = 342 ; B = 6 cm
Total length of the wall = 2400 cm.
Length of each brick = 7 cm.

To calculate number of bricks required, divide 2400 by 7.

Calculating $2400 \div 7$ by box method,

So, for $2400 \div 7$ , the $f i n a l q u o t i e n t$ is $342$ and the $r e m a i n d e r$ is $6$ .

∴ The total number of bricks used to line the wall is $342$ .

And, the length of the wall that remains without any bricks is $6 c m$ .

Comparing these results with the given statement,

Hence, value of A = 342 and
value of B = 6 cm.
