Question

In a park, a wall of length 2400 inch is to be lined with bricks of length 7 inch each. If the bricks are laid without gap, the value of A and B are:

• A. A = 332; B= 6 inches
• B. A = 342; B= 6 inches
• C. A = 332; B = 1 inch
• D. A = 342; B = 1 inch

Answer 1

The correct option is B A = 342; B= 6 inches

Total length of the wall = 2400 inches.
Length of each brick = 7 inches.

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

Calculating $2400÷7$ by box method, we get:


So, for $2400÷7$, the $finalquotient$ is $342$ and the $remainder$ is $6$.

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

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

Comparing these results with the given statement, we get:


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