Number of Astronauts who were goint to Mars is 225 so (a+e+g+f) = 225 of which 26(2/3)% Astronauts were going only on mars and moon so f = 26 (2/3)% of 225 = 60 the number of astronauts who were going to both moon and venus are 33(1/3)% greator than those who were going to all the three missions, so d is 33(1/3)% greator than g the number of astronauts who were going to venus but not moon is 185. so c + e = 185 (means venus and mars)
