Answer:

y = 6

Step-by-step explanation:

given

x is inversely proportional to y

 =  > x =  \frac{k}{y}

 =  > 12 =  \frac{k}{20}

 =  > k = 240

NOW x = 40

 =  > 40 =  \frac{240}{y}

 =  > y = 6

Hope it helps

Answer:

x ∝ 1/y

∴ xy = k                 (where k is constant of proportionality)

k = 12 × 20

∴ When x = 40

k = xy

20 × 12 = 40 × y

∴ y = 6

∴ ANSWER = Y= 6
