3 questions from this set, shown in full with the correct answer and the reasoning behind it. Read them as a study resource.

  1. Q1.A drawing calls for a slot width of 3/83/8 in with a tolerance of +1/16+1/16 in and −1/32-1/32 in.

    What is the maximum acceptable slot width?

    • A.7/16 in✓ Correct answer
    • B.13/32 in
    • C.11/32 in
    • D.1/2 in

    Explanation

    The maximum size uses the plus tolerance, so add 1/161/16 to 3/83/8. Convert to a common denominator first:

    38+116=616+116=716\frac{3}{8} + \frac{1}{16} = \frac{6}{16} + \frac{1}{16} = \frac{7}{16}

    The value 11/3211/32 in is the minimum size, found with the minus tolerance. The value 13/3213/32 in comes from adding 1/321/32 in, which is the wrong tolerance.

  2. Q2.A lot of 1,250 parts is inspected. Three fifths of the lot is checked on the first shift, and 8 percent of the parts checked on that shift are rejected.

    How many first shift parts are rejected?

    • A.100
    • B.48
    • C.60✓ Correct answer
    • D.75

    Explanation

    This needs two steps. First find how many parts the first shift checked:

    1250×35=7501250 \times \frac{3}{5} = 750

    Then apply the rejection rate to that number only:

    750×0.08=60750 \times 0.08 = 60

    The answer 100 applies the 8 percent to the whole lot of 1,250, which is the error the item is built around.

  3. Q3.A rectangular plate measures 120120 mm by 8080 mm. A 2020 mm square notch is then cut out of one corner.

    What is the perimeter of the resulting outline?

    • A.440 mm
    • B.380 mm
    • C.360 mm
    • D.400 mm✓ Correct answer

    Explanation

    The original perimeter is:

    P=2(120+80)=400 mmP = 2(120 + 80) = 400 \text{ mm}

    Cutting a square notch from a corner removes 20 mm from each of two sides, but it adds two new 20 mm edges inside the notch. The removed length and the added length are equal, so the perimeter does not change and stays at 400 mm. The area does go down, and confusing the two is why 360 mm looks tempting.
