Speed = 80 km/hr = 80 * (1000/3600) m/s = 22.22 m/s. Distance covered in 9 seconds (length of train) = Speed * Time = 22.22 m/s * 9 s ≈ 200 meters.

The series alternates between increasing even numbers and subsequent letters. After 8G, the next term is 10I.

The pattern is the first letter decreasing by 1, the number increasing by 3, 4, 5, etc., and the last letter increasing by 3. So, after W17L, it is V23O.

Let the numbers be x and y with x > y. x + y = 45 and x – y = 15. Adding these two equations, 2x = 60, giving x = 30. Therefore, y = 45 – 30 = 15. So, the numbers are 30 and 15.

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°.

Total of 9 numbers = 9 * 50 = 450. Total of first 5 numbers = 5 * 54 = 270. Total of last 3 numbers = 3 * 52 = 156. The 6th number = Total – (Sum of first 5 and last 3) = 450 – (270 + 156) = 24.

A ‘Mixed Economy’ combines elements of both capitalism and socialism, featuring a mix of public and private ownership and control. India is an example of a mixed economy.

Both arguments present valid points. Argument 1 focuses on promoting equality, while Argument 2 emphasizes personal freedom and expression. Both are important considerations in the debate over school uniforms.

Let original length = l and breadth = b. New length = 1.1l, new breadth = 0.9b. New area = 1.1l * 0.9b = 0.99lb. Decrease = 0.01lb, which is a 1% decrease.

At 3:15, the hour and minute hands are at a 90-degree angle. If the hour hand at 3 points East, the minute hand at 15 minutes (or 3 on the clock) will point North.

Let the sum invested at 6% be x. Then, the sum invested at 7% is ₹12,000 – x. The total income is 6% of x + 7% of (₹12,000 – x) = ₹800. Solving for x gives x = ₹6000.

The error is in “have.” “Many a” is followed by a singular noun and verb, so it should be “has.” Correct sentence: “Many a student has failed the exam due to lack of study.”

“Between you and me” is correct. “Between” is a preposition and should be followed by object pronouns, which in this case are “you” and “me.”

A’s 1 day’s work = 1/15, B’s 1 day’s work = 1/10. Work done by A and B in 2 days = 2 * (1/15 + 1/10) = 1/3. Remaining work = 1 – 1/3 = 2/3. B completes 1/10 of work in 1 day, so for 2/3 work, B will take 2/3 * 10 = 6.67 days, which is approximately 7 days.

Let the speed of the boat in still water be b km/hr and the speed of the stream be s km/hr. Upstream speed = b – s, Downstream speed = b + s. From the given equations, solve the two equations 30/(b-s) + 44/(b+s) = 10 and 40/(b-s) + 55/(b+s) = 13 to find b = 7 km/hr.

The sum of the numbers in the diagonal from the top left to the bottom right in any 3×3 grid with distinct numbers from 1 to 9 will always be 15 (for example, 1 + 5 + 9). This is because the middle number (5) is always included in this diagonal, and the remaining two numbers will always sum to 10.
