Find out a set of numbers amongst the four sets of numbers given in the alternatives, which is the most similar to the numbers given in the question. Given:(6, 30, 90)
The relation between 6,30 and 90 is $$6 \times 5 = 30 , 6\times \frac{6}{2} \times 5 = 90$$
So verifying option D, we get $$8 \times 6 = 48, 8 \times \frac{8}{2} \times 6 = 192$$
