  • Question 1/10
    1 / -0.33

    If CUT = 42 and STAR = 56 the how would you code PEN=?

    Solutions

    Logic : the sum of the digits of place value of each letter (-2).

    So, 

    CUT = 3 + 21 + 20 = 44 - 2 = 42 

    and

    STAR = 19 + 20 + 1 + 18 = 58 - 2 = 56

    Similarly, 

    PEN = 16 + 5 + 14 = 35 - 2 = 33


    Hence, option A is the correct answer.

  • Question 4/10
    1 / -0.33
    A and B can do a work in 18 days and 36 days respectively. They worked together for 8 days and then A left. The remaining work was finished by B in?
    Solutions
    Let the total work = 72 units
    Efficiency of A = 72/18 = 4 units/day
    Efficiency of B = 72/36 = 2 units/day
    According to the question,
    They worked together for 8 days
    Work done in 8 days = 6 × 8 = 48 units
    Work left for B = 72 – 48 = 24 units
    ∴ No. of days taken by B to complete the remaining work = 24/2 = 12 days
  • Question 5/10
    1 / -0.33
    If an amount is increased by 20%, by what percent it must be decreased to cancel the increment?
    Solutions

    Let the initial amount = Rs. 100

    Increased amount = 120% of 100 = Rs. 120

    Required percentage to be reduced to get the initial amount 

    Altlernate Approach:
    20%  = 1/5   (means 1 is increased for every 5)
    120% = 6/5   (for every 5 the value becomes 6)

    To go back to the initial value, 1 is reduced from 6

    Then, 1/6 = 100/16% = %

  • Question 6/10
    1 / -0.33
    An article was sold at a gain of 16%. If it had been sold for Rs.36 more, the gain would have been 20%. The cost price of the article is
    Solutions

    At 20% Profit;
    SP = 120% of CP
    and at 16% profit;
    SP = 116% of CP
    So, ATQ
    ⇒ 120% of CP - 116% of CP = 36
    ⇒ (120 – 116)% of CP = 36

    ⇒ 4% of CP = 36

    ⇒ 1% of CP = 9

    ⇒ CP = 900
