November's = \(\frac{2}{5}\) December's
January's = \(\frac{1}{4}\) November's
Let's take the revenue in December \(= 100\) so in November, it will be \(40\) and in January \(10\)
Average of November & January = \(\frac{40+10}{2} = 25\)
December's is four times the average.
Answer E
January's = \(\frac{1}{4}\) November's
Let's take the revenue in December \(= 100\) so in November, it will be \(40\) and in January \(10\)
Average of November & January = \(\frac{40+10}{2} = 25\)
December's is four times the average.

December revenue=100
November revenue=2*100/5=40
January revenue=1*40/4=10
Required=100:(40+10)/2 = 100:25=4. Answer is E.
November revenue=2*100/5=40
January revenue=1*40/4=10
Required=100:(40+10)/2 = 100:25=4. Answer is E.
