    30
    25
    35
    40
    45
    Option B
    Quantity of milk = 375 * 16/25 = 240
    quantity of water = 375 * 9/25 = 135
    ATQ,
    240/135 + x = 3/2
    3x + 405 = 480

  2. A and B alone can complete a piece of work in 24 days and 20 days respectively. If efficiency of C is 60% more than A, then find in how many days C complete the work ?
    15 days
    17 days
    20 days
    25 days
    30 days
    Option A
    LCM of 24 and 20 = 120
    efficiency of A = 120/24 = 5
    efficiency of B = 120/20 = 6
    efficiency of C = 5 * 160/100 = 8
    time required = 120/8 = 15 days

     

  3. A shopkeeper marked up an article 25% above its cost price and allowed a discount of 40% on it. If shopkeeper made a loss of rs.128, then find what is the cost price ?
    620
    340

    480
    Option D
    Let CP of article = 100x
    MP of article = 100x * 125/100 = 125x
    SP of article = 125x * 60/100 = 75x
    loss = 100x – 75x = 25x
    CP of article = 128/25x * 100x = 512

    30250
    28140
    34400
    Option C
    Rate of compound interest for half yearly = 20/2 = 10%
    rate of CI after 1 year = 10 + 10 + 10 * 10/100 = 21%
    CI = 25000 * 21/100 = 5250
    amount = 25000 + 5250 = 30250
