At a certain organisation, the number of male members went up by 14% in the year 2001 from year 2000, and the number of females members went down by 6% in the same time period. If the total membership at the organisation went up by 1.2% from the year 2000 to 2001, what was the ratio of male members to female members in the year 2000? Choose the correct choice from the following answers
A) 1:2 B) 1:3 C) 2:3 D) 3:2 E) 4:7
men increase by 14% ==&gt; 1.14M = males in 2001   women decrease by 6% ==&gt; 0.94F = women in 2001   total employees increase by 1.2% ==&gt; 1.012*(M + F) = total number of employees in 2001   Obviously   (males in 2001) + (females in 2001) = total number of employees in 2001   1.14M + 0.94F = 1.012*(M + F)   1.14M + 0.94F = 1.012M + 1.012F   1.14M - 1.012M = 1.012F - 0.94F   0.128M = 0.072F   M/F = (0.072)/(0.128) = 72/128 = 4/7   Answer =(4:7)
