5. Q5 · Profit & Loss

   A shopkeeper marks his goods 40% above the cost price but allows a discount of 20%. His actual profit percentage is:

   • A. 12%
   • B. 15%
   • C. 18%
   • D. 10%
   Answer and solution

   Answer: A

   Let CP = 100. Marked Price = 140. After 20% discount, SP = 140 × 0.8 = 112. Profit = 112 - 100 = 12, so profit% = 12%.

6. Q6 · Percentage

   If 35% of a number is 140, what is 60% of that number?

   • A. 240
   • B. 220
   • C. 200
   • D. 260
   Answer and solution

   Answer: A

   35% of the number = 140, so the number = 140 × (100/35) = 400. Therefore, 60% of 400 = 240.

7. Q7 · Time & Distance

   A train 150 meters long crosses a platform 250 meters long in 20 seconds. What is the speed of the train in km/h?

   • A. 60 km/h
   • B. 72 km/h
   • C. 80 km/h
   • D. 90 km/h
   Answer and solution

   Answer: B

   Total distance = 150 + 250 = 400 meters. Speed = 400/20 = 20 m/s = 20 × 18/5 = 72 km/h.

8. Q8 · Statements & Conclusions

   Statement: All teachers are educated. Some educated people are writers. Conclusion I: All teachers are writers. Conclusion II: Some writers are educated. Which conclusion(s) logically follow(s)?

   • A. Only conclusion I
   • B. Only conclusion II
   • C. Both I and II
   • D. Neither I nor II
   Answer and solution

   Answer: B

   Conclusion I does not follow as there is no direct link between teachers and writers; Conclusion II follows since some educated people are writers.

9. Q9 · Trigonometry

   If tan A = 4/3, what is the value of (sin A + cos A)?

   • A. 7/5
   • B. 6/5
   • C. 8/5
   • D. 9/5
   Answer and solution

   Answer: A

   Since tan A = 4/3, we have sin A = 4/5 and cos A = 3/5 (for acute angle). Thus, sin A + cos A = 4/5 + 3/5 = 7/5.

10. Q10 · Classification

    Find the odd one out from the following:

    • A. Eagle
    • B. Sparrow
