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%.

3 / 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.

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.

The perimeter of an equilateral triangle is 18 cm. Find its area.

Side of the triangle = Perimeter/3 = 18/3 = 6 cm. Area of an equilateral triangle = (√3/4) * side² = (√3/4) * 6² = 17.320 cm².

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.

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.

24 / 50

A cube has a total surface area of 216 cm². Find the length of one side of the cube.

Total surface area of a cube = 6 * side². 216 = 6 * side², giving side² = 36, so the side = 6 cm.

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.

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.

36 / 50

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.

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°.
