  • (A) 15 days
  • (B) 18 days
  • (C) 20 days
  • (D) 24 days
💬 Discuss
✅ Correct Answer: (C) 20 days

Explanation: A+B = 1/10, B+C = 1/15, A+C = 1/12. Adding → 2(A+B+C) = 1/10 + 1/15 + 1/12 = 1/4 → A+B+C = 1/8. A = (A+B+C) - (B+C) = 1/8 - 1/15 = 1/20.

📊 Math

  • (A) 1/4
  • (B) 1/3
  • (C) 2/5
  • (D) 3/5
💬 Discuss
✅ Correct Answer: (B) 1/3

Explanation: A: 3/15 = 1/5, B: 9/45 = 1/5. Completed = 2/5 → Remaining = 3/5.

📊 Math
Q. A is 60% as efficient as B. If together they complete a work in 15 days, in how many days can A alone complete it?
  • (A) 25 days
  • (B) 30 days
  • (C) 37.5 days
  • (D) 40 days
💬 Discuss
✅ Correct Answer: (C) 37.5 days

Explanation: Let B = 1, A = 0.6. Together = 1.6. If work = 1 unit → time = 15 days → work per day = 1/15. A = 0.6 × 1/1.6 = 3/8. So A takes 15 ÷ (3/8) = 40 days? Correct solving: A efficiency = 3/8 → time = 1/(3/8) = 8/3 × 15 = 37.5.

📊 Math

✅ Correct Answer: (C) 30 days

Explanation: A works 5 days → 5/15 = 1/3. Remaining 2/3 completed in 5 days by A+B. A = 1/15, so B = 2/3 ÷ 5 - 1/15 = 1/30.

📊 Math
