Worker is paid Rs.20 per day worked and forfeits Rs.3 per idle day. In 60 days he got Rs.280. Idle days:

  1. 15
  2. 20
  3. 40
  4. 30
Show answer and solution

Correct answer: C. 40

1. Let idle days = i. Worked days = 60 − i. 2. 20(60−i) − 3i = 280 → 1200 − 20i − 3i = 280 → 23i = 920. 3. i = 920/23 = 40. So 40 days idle. _Source: KMAT Karnataka 2023 PYQ Q.33_

Solve: 2x + 3 = 11.

  1. x = 3
  2. x = 4
  3. x = 5
  4. x = 6
Show answer and solution

Correct answer: B. x = 4

1. Subtract 3 from both sides: 2x = 8. 2. Divide by 2: x = 4. 3. Verify: 2(4) + 3 = 11 ✓. _Source: KMAT Karnataka 2022 PYQ Q.75_

If 5x − 7 = 3x + 5, then x =

  1. 6
  2. 5
  3. 4
  4. 3
Show answer and solution

Correct answer: A. 6

1. Move x terms left, constants right: 5x − 3x = 5 + 7. 2. 2x = 12 → x = 6. 3. Verify: 5(6)−7 = 23; 3(6)+5 = 23 ✓. _Source: KMAT Karnataka 2022 PYQ Q.77_
