A contractor estimates that $3$ persons could rewire Jasminders house in $4$ days. If he uses $4$ persons instead of three, how long should they take to complete the job?
$8$ days
$3$ days
$9$ days
$4$ days

The given example is of inverse proportionality

$I$ $I I$

No. of persons $3$ $4$

No. of days $4$ $x$

By inverse proportionality,

$3 \times 4 = 4 \times x$

$x = 3$ days

Answer is option B
