Worked practice questions

If 5 books and 4 pens cost Rs.230 and 4 books and 5 pens cost Rs.220, then cost of 1 book is:

  1. Rs. 30
  2. Rs. 25
  3. Rs. 35
  4. Rs. 20
Show answer and solution

Correct answer: A. Rs. 30

1. Let book = b, pen = p. 5b + 4p = 230; 4b + 5p = 220. 2. Add: 9b + 9p = 450 → b + p = 50. Subtract: b − p = 10. 3. So b = 30, p = 20. _Source: KMAT Karnataka 2022 PYQ Q.119_
