2. A family's monthly budget of ₹60,000 is shown in a pie chart: rent 30%, food 25%, transport 10%, savings 20%, others 15%. What is the central angle for food, and how much more is spent on rent than saved?

   Food's angle is 25% of 360 = 90 degrees. Rent is ₹18,000 and savings ₹12,000, so rent exceeds savings by ₹6,000. In general, angle = percent x 3.6, and amount = percent x total / 100.

3. How do you quickly approximate a value like '3,487 is what percent of 15,012?' in a timed data interpretation section?

   Round both numbers to friendly values close to the originals: 3,500 / 15,000 = 7/30, about 23.3%. The exact value is 23.23%, so the estimate is enough to pick the right option when choices are reasonably far apart.

4. Plant A produced 450, 520 and 600 units over three years, and Plant B produced 300, 390 and 480 units. What is B's total output as a percentage of A's, and in which year was B's output closest to A's?

   B's total (1,170) is about 74.52% of A's total (1,570). Year by year, B/A is 66.7%, 75% and 80%, so B came closest to A in the third year, even though the gap in units (120) was smallest in the first and third years.
