Question

can someone solve this??​

Answer 1

Step-by-step explanation:

inverse proportion as worker increase day decrease so

if x=12 and y=6

$x= k \times \frac{1}{y} \\ \\ 12 = k \times \frac{1}{6} \\ \\ k = 72$

if x is n and y is 24 so

$n = k \times \frac{1}{y} \\ \\ n = 72 \times \frac{1}{24} \\ \\ n = 3$

if x is 4 and y is d so

$x = k \times \frac{1}{y} \\ \\ 4 = 72 \times \frac{1}{d} \\ \\ d = 18$
