Answer: A) 15 Explanation: Combined efficiency of all the three boats = 60 passenger/trip    Now, consider option(a)   15 trips and 150 passengers means efficiency  of B1 =  10 passenger/trip    which means in carrying 50 passengers B1 must has taken 5 trips. So the rest trips equal to 5 (10-5 = 5) in which B2 and B3 together carried remaining 250 (300 - 50 = 250) Passengers.   Therefore the efficiency of B2 and B3 = 250/5 = 50 passenger/trip     Since, the combined efficiency of B1, B2 and B3 is 60. Which is same as given in the first statement hence option(a) is correct.
