Explanation:

Explanation :
Number of male teachers who teach Geography = 2/3 * 23/100 * 1800 = 276
Number of male teachers who teach History = 1/2 * 27/100 * 1800 = 243
% of female teachers who teach Biology = % of female teachers who teach Biology i.e 50%
Therefore Number of male teachers who teach Biology = 50/100 * 12/100 * 1800 = 108
Total = 276 + 243 + 108 = 627
