  • Question 1/10
    1 / -0.25
    When a student weighing 45 kg left a class, the average weight of the remaining 59 students increased by 200g. What is the average weight of the remaining 59 students?
    Solutions
    Let the average weight of the 59 students be A.
    Therefore, the total weight of the 59 of them will be 59A.
    The questions states that when the weight of this student who left is added, the total weight of the class = 59A + 45
    When this student is also included, the average weight decreases by 0.2 kgs.
    = A - 0.2
    => 59A + 45 = 60A - 12
    => 45 + 12 = 60A - 59A
    => A = 57.
  • Question 2/10
    1 / -0.25
    A man moves upstream in 6 hours in a boat at a speed of 20km/h. Then he rows down in 3 hours. What is the rate of flow of the stream?
    Solutions
    As the man moves upstream in 6 hours at a speed of 20km/h, the length of the stream = Speed × Time = 20 × 6 = 120 km
    So, speed of the boat downstream = Distance/Time = 120/3 = 40km/h
    So, let the speed of the boat in still water be x km/h and the rate of flow of the stream be y km/h.
    For upstream, x - y = 20
    For, downstream, x + y = 40
    On solving the above two equations, we get y = 10km/h.
    So, rate of flow of the stream is 10km/h.

  • Question 4/10
    1 / -0.25
    Piyush, Vikas and Manav enter into a partnership. Piyush invests some amount at the beginning. Vikas invests double the amount after 6 months and Manav invests thrice the amount invested by Piyush after 8 months from start of business. They earn a profit of Rs. 45000 at the end of the year. What is Manav's share in the profit?
    Solutions
    Let Piyush 's investment = Rs. x
     Vikas's investment = Rs. 2x Rs.
    Manav's investment = Rs. 3x
    Ratio of the equivalent capitals of Piyush,
    Vikas and Manav, respectively
    =x × 12 : 2x × 6 : 3x × 4
    = 12x : 12x : 12x = 1 : 1 : 1
    Clearly, the profit will be shared equally
    Manav's share = Rs. × 45000 = Rs. 15000
