Solution for Quant Question of the day: 257

using alligation

40% grads                                70% non grads

                   60% boys        

10                             :                   20

hence ration of grads to non grads is 10:20 = 1:2

hence % of grads = (grads/total)*100 = 1/3*100 = 33.33%
