Question

A road transport accepts 72% of the auto meters in working condition. How many will he examine to accept 270 auto meter

Answer 1

72 auto meters are accepted if it examines 100 auto meters

1 auto meter is accepted if it examines (100/72) auto meters

270 auto meters are accepted if it examines (100*270/72) auto meters

                                                                         = (100*30/8) auto meters

                                                                          = (25*30/2) auto meters

                                                                          = (25*15) auto meters

                                                                          = 375 auto meters.

(Ans): 375 auto meters.
