What is the difference between the total number of the male visitors in September 2012 and October 2012 together and the total number of male visitors in November 2012 and December 2012 together?

Total number of the male visitors in September 2012 = $$\frac{4}{11} \times 55,000 = 20,000$$

Total number of the male visitors in October 2012 = $$\frac{3}{5} \times 75,000 = 45,000$$

=> Sum = $$20,000 + 45,000 = 65,000$$

Total number of male visitors in November 2012 = $$\frac{5}{8} \times 65,000 = 40,625$$

Total number of male visitors in December 2012 = $$\frac{3}{7} \times 1,26,000 = 54,000$$

=> Sum = $$40,625 + 54,000 = 94,625$$

$$\therefore$$ Difference = $$94,625 - 65,000 = 29,625$$
