    What amount did Jean earn from the commission on her sales in the first half of 1988 ?

    (1) In 1988 Jean's commission was 5 percent of the total amount of her sales.
    (2) The amount of Jean's sales in the second half of 1988 averaged $10,000 per month more than in the first half
    Statement 1:
    If Jean's total sales = $100, then her commission = 5% of 100 = $5.
    If Jean's total sales = $1000, then her commission = 5% of 1000 = $50.
    Since her commission can be different values, INSUFFICIENT.

    Statement 2:
    Since the commission rate is unknown, INSUFFICIENT.

    Statements combined:
    Case 1: Sales for the first half of the year = $10000 per month, sales for the second half of the year = $20000 per month
    In this case:
    Total sales = (6*10000) + (6*20000) = $180,000.
    Commission = 5% of 180,000 = $9,000.

    Case 2: Sales for the first half of the year = $20000 per month, sales for the second half of the year = $30000 per month
    In this case:
    Total sales = (6*20000) + (6*30000) = $300,000.
    Commission = 5% of $300,000 = $15,000.

    Since the commission can be different values, INSUFFICIENT.

    The correct answer is E.

    Required: How much did Jean earn in commission in first half of 1988

    Statement 1: In 1988 Jean's commission was 5 percent of the total amount of her sales
    Since we do not know the total sales, we cannot find the commission.
    INSUFFICIENT

    Statement 2: The amount of Jean's sales in the second half of 1988 averaged $10,000 per month more than in the first half
    Nothing discussed about the commission percentage.
    Clearly INSUFFICIENT

    Combining both statements:
    We just know the difference between the sales of both halves, but not the absolute values.
    The commission will depend on the absolute values.
    Still INSUFFICIENT

    Correct Option: E

    I have a question for you. How long did it take you to solve this ? And did you solve this correctly ?

    This is hardly a 1 Min question and just like I explained in one of the problems you posted, if some key principles are etched in your mind you do not have to spend much time on a problem. It is just like knowing multiplication table of 5. You can never forget it and it is always at ur finger tips that any multiple of 5 can either have last digit as 5 or 0.

    Statement 1:INSUFFICIENT ( 10 secs)

    Again as the question is EXACT value Q, only % will not give you answer.

    Statement 2: INSUFFICIENT (15 secs)

    The variable X is first half sales. This statement gives no info about X.

    COMBINE: INSUFFICIENT (20-30 secs)

    You have the % but you still do not have X so no point thinking further.

    Answer : E

    You saved almost more than 1 min by keeping some simple rules at tips.

    Cheers
