GAT Quantitative Reasoning MCQs

A's capital-time is 2 × 6 + 4 × 6 = 36 units.
B's is 3 × 12 = 36 units, so profits are equal.

A 20% profit gives a selling price of Rs. 960.
Since this is 80% of marked price, marked price = 960/0.8 = Rs. 1,200.

He charges for 1,000 grams but supplies only 900 grams.
Gain percentage is 100/900 × 100 = 11 1/9%.

The selling price is 80% of the marked price.
Thus, marked price = 960 ÷ 0.80 = Rs. 1,200.

Sales tax is 12% of Rs. 5,000, or Rs. 600.
The total payable amount is Rs. 5,600.

Commission is 6% of total sales.
Thus, 0.06 × 250,000 = Rs. 15,000.

The taxed price is 115% of the original price.
So the original is 2,300 ÷ 1.15 = Rs. 2,000.

For inverse variation, xy is constant.
Since 12 × 4 = 48, x = 48/6 = 8.

Using SI = PRT/100, 900 = P × 6 × 3/100.
Solving gives P = Rs. 5,000.

Two centimeters represent 100,000 centimeters in reality.
Since 100,000 cm = 1 km, the answer is 1 kilometer.

Rate = SI × 100 ÷ (P × T).
Thus, 800 × 100 ÷ (4,000 × 5) = 4%.

The difference of ratio parts is 5, corresponding to 35.
One part is 7, so the larger number is 9 × 7 = 63.
