A square and a rectangle have the same area. The rectangle’s length is 20% more than its breadth. If the side of the square is 30 cm, find the dimensions of the rectangle.

Area of the square = 30 cm × 30 cm = 900 cm². Let the breadth of the rectangle be x cm. Length = 1.2x cm. Area = x × 1.2x = 900 cm². Solving for x gives x ≈ 27 cm, so the length is 1.2 × 27 ≈ 32.4 cm.

Choose the odd one out: Triangle, Pentagon, Hexagon, Cube

‘Cube’ is the odd one out as it is a 3-dimensional shape, while the others are 2-dimensional polygons.

8 / 50

The length and breadth of a rectangle are increased by 20% and 30% respectively. What is the percentage increase in the area?

Let original length = l and breadth = b. New length = 1.2l, new breadth = 1.3b. New area = 1.2l * 1.3b = 1.56lb. Increase = 1.56lb – lb = 0.56lb, which is a 56% increase.

A and B can complete a task in 10 days and 15 days respectively. They start working together, but after 4 days B leaves. In how many more days will A complete the remaining work?

A’s 1 day’s work = 1/10, B’s 1 day’s work = 1/15. Together, in 4 days, they complete 4*(1/10 + 1/15) = 2/5 of the work. Remaining work = 1 – 2/5 = 3/5. A will complete this in 3/5 * 10 = 6 more days.

Statement and Assumption: Statement: “Use XYZ brand detergent for longer-lasting clothes,” an advertisement. Assumption: A) XYZ brand detergent is better than other brands. B) People want their clothes to last longer.

The most directly implicit assumption in the advertisement is that people want their clothes to last longer (Assumption B). The advertisement suggests this benefit to attract customers. Assumption A is a marketing claim, not necessarily an implicit assumption of the statement.

Cause and Effect: If heavy rain causes flooding and there is flooding in the city, what can be inferred?

While heavy rain might cause flooding, flooding can also be caused by other factors like poor drainage. Therefore, we cannot definitively infer that it has rained heavily.

13 / 50

Cause and Effect: Heavy rainfall led to flooding in the region. The government has announced relief measures. What can be inferred?

A man sells two watches for ₹2000 each. On one, he gains 5% and on the other, he loses 5%. Find his total gain or loss percent.

Gain or loss is calculated on cost price. Let the cost price of the first watch be x and the second y. 105% of x = 95% of y = ₹2000. The overall loss = (Selling price of both – Cost price of both) = 4000 – (x + y). Calculating x and y and then the difference shows a 0.25% loss overall.

The area of a parallelogram is 180 cm², and its altitude is 15 cm. Find the length of the base.

Area of a parallelogram = base * height. Let the base be x cm. Then, x * 15 = 180. Solving for x gives x = 12 cm.

21 / 50

If 35% of a number is 175, find 50% of the number.

Let the number be x. 35% of x = 175, so x = 175 * 100 / 35 = 500. 50% of 500 = 250.

22 / 50

‘Gross National Happiness’ is a measure of development used by which country?

23 / 50

An article is sold for ₹816, gaining 20%. Find its cost price.

Let the cost price be ₹x. Selling price = x + 20% of x = 1.2x = ₹816. Solving gives x = ₹680.

24 / 50

A shopkeeper marks his goods 20% above his cost price and gives a discount of 10%. What is his gain percent?

If the cost price is ₹100, the marked price is ₹120. A 10% discount on ₹120 is ₹12, so the selling price is ₹108. The gain is ₹108 – ₹100 = ₹8, which is an 8% gain.

25 / 50

The radius of a circle is increased by 20%. Find the percentage increase in its area.

Original area = πr². New radius = 1.2r. New area = π(1.2r)² = 1.44πr². The percentage increase in area = (1.44πr² – πr²) / πr² × 100% = 44%.

26 / 50

The ratio of the speeds of two trains is 3:4. If the second train runs 400 km in 4 hours, find the speed of the first train.

Speed of the second train = 400 km / 4 hrs = 100 km/hr. Using the ratio of speeds, 3:4, speed of the first train = 3/4 × 100 = 75 km/hr.

In a ΔPQR, if PQ = QR and ∠PQR = 100°, find ∠QPR.

Since PQ = QR, ΔPQR is isosceles. The angles opposite the equal sides are equal, so ∠QRP = ∠QPR. Let each of these angles be x. Then, x + x + 100° = 180° (sum of angles in a triangle). Solving gives x = 40°.

A train moving at 60 km/hr overtakes another train, half its length, moving in the same direction at 40 km/hr in 30 seconds. What is the length of the first train?

The relative speed = 60 km/hr – 40 km/hr = 20 km/hr = 20 * (1000/3600) m/s = 5.56 m/s. Let the length of the first train be L meters. Then, the second train’s length is L/2 meters. The total distance covered in overtaking = L + (L/2) = 1.5L meters. Time taken = 30 seconds. So, 1.5L = 5.56 * 30, giving L ≈ 200 meters.
