**Questions with answers from GRE Quantitative reasoning section**

**Question**: A rectangular garden measuring 30 meters by 40 meters is to be surrounded by a walkway of uniform width. If the area of the walkway is to be one-fourth the area of the garden, what must be the width of the walkway?

**Answer**: Let the width of the walkway be ( w ) meters. The area of the garden is ( 30 \times 40 = 1200 ) square meters. The area of the walkway is ( \frac{1}{4} \times 1200 = 300 ) square meters. The dimensions of the garden plus walkway are ( (30 + 2w) ) by ( (40 + 2w) ). The area of the garden plus walkway is ( (30 + 2w)(40 + 2w) ). The area of just the walkway is the total area minus the area of the garden, which gives us the equation ( (30 + 2w)(40 + 2w) – 1200 = 300 ). Solving for ( w ), we find that ( w = 5 ) meters.

**Question**: A company sells two products, P and Q. The profit from selling one unit of P is $20 and from Q is $30. Last month, the company sold a total of 200 units and made a profit of $4500. How many units of each product were sold?

**Answer**: Let ( x ) be the number of units of P sold and ( y ) be the number of units of Q sold. We have two equations: ( x + y = 200 ) (total units sold) and ( 20x + 30y = 4500 ) (total profit). Solving this system of equations, we get ( x = 150 ) and ( y = 50 ).

**Question**: If the probability that an event will occur is ( \frac{2}{3} ), what is the probability that the event will not occur twice in two independent trials?

**Answer**: The probability that the event will not occur in one trial is ( 1 – \frac{2}{3} = \frac{1}{3} ). Since the trials are independent, the probability that the event will not occur in both trials is ( \left(\frac{1}{3}\right)^2 = \frac{1}{9} ).

**Question**: A train travels from Station A to Station B at a speed of 60 km/h and returns at a speed of 90 km/h. What is the average speed for the round trip?

**Answer**: The average speed for a round trip is given by the formula Average Speed=Speed1+Speed22×Speed1×Speed2 . Plugging in the values, we get Average Speed=60+902×60×90=15010800=72 km/h .

**Question**: If the price of an item is increased by 25% and then decreased by 20%, what is the net percentage change in the price?

**Answer**: Let the original price be $100. After a 25% increase, the new price is $125. A 20% decrease on $125 is $25, so the final price is $125 – $25 = $100. The net percentage change is 0%.

**Question**: A rectangle’s length is twice its width. If the perimeter of the rectangle is 60 cm, what are its dimensions?

**Answer**: Let the width be ( w ) cm. Then the length is ( 2w ) cm. The perimeter is ( 2(w + 2w) = 60 ). Solving for ( w ), we get ( w = 10 ) cm and the length is ( 20 ) cm.

**Question**: A company has two types of machines, type A and type B. Type A machines can produce 100 units per hour, while type B machines produce 80 units per hour. If the company operates 5 type A machines and 3 type B machines, how many units are produced in 4 hours?

**Answer**: In 4 hours, type A machines produce ( 5 \times 100 \times 4 = 2000 ) units, and type B machines produce ( 3 \times 80 \times 4 = 960 ) units. The total production is ( 2000 + 960 = 2960 ) units.

**Question**: A school has 1200 students. If 40% are boys, how many girls are there in the school?

**Answer**: If 40% are boys, then 60% are girls. The number of girls is ( 0.60 \times 1200 = 720 ).

**Question**: A ladder leans against a wall forming a 60-degree angle with the ground. If the top of the ladder is 15 feet from the ground, how long is the ladder?

**Answer**: Using the sine function, ( \sin(60^\circ) = \frac{\text{opposite}}{\text{hypotenuse}} ). The length of the ladder (hypotenuse) is ( \frac{15}{\sin(60^\circ)} \approx 17.32 ) feet.

**Question**: A car travels the first third of a certain distance with a speed of 30 km/h, the next third with a speed of 50 km/h, and the last third with a speed of 20 km/h. What is the average speed for the entire trip?

**Answer**: Let the total distance be ( 3d ). The time for each third is ( \frac{d}{30} ), ( \frac{d}{50} ), and ( \frac{d}{20} ) hours, respectively. The total time is ( \frac{d}{30} + \frac{d}{50} + \frac{d}{20} ) hours. The average speed is ( \frac{3d}{\frac{d}{30} + \frac{d}{50} + \frac{d}{20}} \approx 28.57 ) km/h.

**Question**: In a class of 50 students, 18 play football, 17 play basketball, and 15 play both. How many students do not play either sport?

**Answer**: Using the principle of inclusion-exclusion, the number of students playing at least one sport is ( 18 + 17 – 15 = 20 ). Therefore, ( 50 – 20 = 30 ) students do not play either sport.

**Question**: A fruit seller buys oranges at $4 per dozen and sells them at $1 for 3 oranges. How many oranges must he sell to make a profit of $20?

**Answer**: The cost price per orange is ( \frac{4}{12} = \frac{1}{3} ) dollars. The selling price per orange is $1 for 3, or ( \frac{1}{3} ) dollars. The profit per orange is ( \frac{1}{3} – \frac{1}{3} = 0 ), so he cannot make a profit by selling oranges at this price.

**Question**: A tank is filled by Pipe A in 2 hours and by Pipe B in 3 hours. When both pipes are opened, how long will it take to fill the tank?

**Answer**: Pipe A’s rate is ( \frac{1}{2} ) tank/hour, and Pipe B’s rate is ( \frac{1}{3} ) tank/hour. Together, they fill ( \frac{1}{2} + \frac{1}{3} = \frac{5}{6} ) tank/hour. The tank will be filled in ( \frac{1}{\frac{5}{6}} = 1.2 ) hours, or 1 hour and 12 minutes.
