    Q11) A train A starts from town A for town B at 6 am. Another train B leaves town C, which is 600km from town A in the direction of town B, at 7 am. The two trains meet each other at 11 am at a place which is exactly between towns A and C. thereafter they continue to their destination. If train A reaches B 3.5 hours after train B reaches A, find the distance between the towns A and B?

    (A) 750 km
    (B) 720 km
    (C) 675 km
    (D) 650 km

    The trains meet at 11 am at the place which is 300km from A & C.
    Speed of train A = 300/5 = 60 km/h
    Since train B covers the distance upto the midpoint in 4 hours, it will reach town A 4 hours after they meet.
    Hence train A will reach town B 7.5 hours after they meet.
    Total time taken by train A to reach town B = 5+7.5 = 12.5 hours
    Hence distance between A and B = 750 km.

    @Sri-Kanth Correct!
    Short trick : 375=125 * 3 and N mod 3 = 1. Only 1st option satisfy
    Method full : N mod 125 = 864/125 (last three digits of N mod 125) = 114
    N mod 3 = 1
    SO N = 125k + 114
    N = 3p + 1
    125k + 113/3 = p
    K= 2 p=121
    So rem = 121 * 3 + 1 = 364

    @Sri-Kanth Correct.
    Let A have 100 chocolates and B have 20% more, ie 120 chocolates.
    A has 2/3 rd chocolate of C. So C = 120 * 3/2 = 150 chocolates.
    B has 130 less from A + C together.
    So percentage will be (130/250) * 100 = 52%

    @Sri-Kanth Correct.
    40% work is completed in 40 hours (as 64 people are working in all the days, ignore 64 from calculations)
    Remaining work = 60%
    Required work hours = 60
    Remaining Days = 4
    So required work hours/day = 60/4 = 15
