Number of households with exactly 2 televisions = 24% of Total = k (given)
=> \(\frac{24}{100 * Total}\) = k
=> Total = k * \(\frac{25}{6}\)
The number of households with exactly 4 televisions = 20% of Total = \(\frac{20}{100}\) * k * \(\frac{25}{6}\) = \(\frac{5k}{6 }\)
So, Answer will be D
Hope it helps!

Simple solution, assume that there are 100 TV sets in total
So, The exact number of household with 2 TV sets would be 24 and with 4TV sets would be 20
Given 24=k ; then 20=?
24 *(20/24) = k *(20/24) that gives you 20=5/6k
So, The exact number of household with 2 TV sets would be 24 and with 4TV sets would be 20
Given 24=k ; then 20=?
24 *(20/24) = k *(20/24) that gives you 20=5/6k
