Mark (✓) against the correct answer:

14 workers can build a wall in 42 days. One worker can build it in

(a) 3 days

(b) 147 days

(c) 294 days

(d) 588 days


(d) 588 days

Let one worker take x days to build the wall.

Clearly, one worker will take more days to finish the work.

So, it is a case of inverse proportion

Now, $14 \times 42=1 \times x$

$\Rightarrow x=14 \times 42$

$\Rightarrow x=588$

∴ One worker can build the wall in 588 days.
