Question

Saplings are to be planted on the roadside having length 6 km 885 m. The first sapling was planted 15 m away from the starting point. Similarly, the second sapling was planted 15 m away from the first one and so on.
How many saplings will be planted in total?

• A. 345
• B. 381
• C. 454
• D. 459

Answer 1

The correct option is D 459

Total length of the road = 6 km 885 m.
Each sapling has a distance of 15 m.

∴ To get number of saplings, divide 6 km 885 m by 15 m.

Convert 6 km 885 m to $m$,
6 km 885 m = 6 × 1000 m + 885 m
= 6885 m

So, here,
Divisor = $15$
Dividend = $6885$

$$\begin{array}{c}459\\ 156885\\ -\underset{–}{60}2\\ 88\\ -\underset{–}{75}\\ 135\\ -\underset{–}{135}\\ 0\end{array}$$
Thus, a total of 459 saplings will be planted.
