Question

Observe the following picture and find the total number of bricks transferred by each lift.

Accepted Answer

Given,

In the first lift,

The number of bricks carried for $1$ , round $= 4$ .

The total number of rounds $= 29$ .

In, the second lift,

The number of bricks carried for $2$ , round $= 5$ .

The total number of rounds $= 44$ .

In, the third lift,

The number of bricks carried for $3$ , round $= 6$ .

The total number of rounds $= 55$ .

We, need to find the total number of bricks transferred by each lift.

Therefore,

The total number of bricks transferred by each lift $=$ Total number of rounds $\times$ Number of bricks carried in each round.

The total number of bricks transferred by lift $1 = 29 \times 4$

$\begin{matrix} 2 & 9 \\ \times & 4 \\ 1 & 1 & 6 \end{matrix}$

The total number of bricks transferred by lift $2 = 44 \times 5$

$\begin{matrix} c a r r y & 2 \\ 4 & 4 \\ \times & 5 \\ 2 & 2 & 0 \end{matrix}$

The total number of bricks transferred by lift $3 = 55 \times 6$

$\begin{matrix} c a r r y & 3 \\ 5 & 5 \\ \times & 6 \\ 3 & 3 & 0 \end{matrix}$

Hence, the total number of bricks transferred by each lift are:

Lifts Total number of bricks

Lift $1$ $116$

Lift $2$ $220$

Lift $3$ $330$
