given
4000 = k * 1/21000
k = 84 * 10^6
now
twh = 84*10^6/ 6000 ; 14,000
IMO E

Recall that if y varies inversely with x, we let k = the constant of proportionality, and we set up the following equation:

y = k * (1/x) = k/x

For this question, we can create the equation:

4000 = k/21,000

k = 4000 * 21,000

Now we can let x = the number of two wheelers sold when 6000 four wheelers were sold and create the equation:

6000 = (4000 * 21,000) / x

6000x = 4000 * 21,000

6x = 4 * 21,000

x = 14,000

Answer: E
