UGC NET Paper 1: Held on 6th Jan 2025 Shift 1 (Previous Year Paper)

Total number of cornmeal hotcakes sold by A and D together = 320+420 = 740.

For number of swedish hotcakes sold by A :

American - cornmeal = 40

American hotcakes = 360.

Number of Swedish hotcakes sold = 1200 - 320 - 360 = 520.

Difference = 740 - 520 = 220.

Number of cornmeal hotcakes sold on tuesday : 1.2 × 280 = 336.

Number of american hotcakes sold = 320.

\(\frac{american hotcakes}{swedish hotcakes}=\frac{4}{5}=\frac{320}{x}\)

number of swedish hotcakes sold = 400.

total = 400+336+320 = 1056.

Number of american hotcakes  sold by A = 320+40 = 360.

For number of swedish hotcakes sold by C :

American - cornmeal = 80

American hotcakes = 440.

Number of Swedish hotcakes sold = 1000 - 440 - 360 = 200.

reqd. percentage = \(\frac{160}{200}\times100=80\)%

Number of american hotcakes sold by C = 360+80 = 440.

For number of swedish hotcakes sold by D :

American - cornmeal = 40

American hotcakes = 460.

Number of Swedish hotcakes sold = 1320 - 420 - 460 = 440.

 Ratio = 1:1.

Number of Swedish hotcakes sold = 100 - 40 - 35 = 25% of the total hotackes.

Total hotcakes = 1320 - 120 = 1200.

Number of Swedish hotcakes = 0.25 × 1200 = 300.

• Rule of Negativity: From two negative premises no conclusion follows. Also, a negative conclusion requires exactly one negative premise; if a premise is negative, the conclusion must be negative.
• Middle Term Distribution: The middle term must be distributed at least once in the premises (to link the major and minor terms); failure to do so yields the fallacy of the undistributed middle.
• Rule of Three Terms: A valid categorical syllogism contains exactly three and only three terms; violating this causes the fallacy of four terms.
• Common Syllogistic Fallacies
• Fallacy of Four Terms: More than three terms are used.
• Fallacy of Undistributed Middle: Middle term is not distributed in either premise.
• Fallacy of Exclusive Premises: Both premises are negative (no conclusion follows).
