• # question_answer If 945 balls can be put in 7 boxes, then how many balls can be put in 9 such boxes? A) 1045                  B)       1215C) 1165                   D)        1385E) None of these

Explanation: Option (b) is correct. Given that in 7 boxes, the number of balls that can be put = 945 Therefore, in 1 box, the number of balls that can be put = $945\div 7$ = 135 Hence, in 9 boxes, the number of balls that can be put = $135\times 9$ = 1215 Rest of the options is incorrect because of the correctness of option (b).
