Piece rate = Rs.10/unit; A earns Rs.2,400 and B earns Rs.3,900 under straight piece-rate.

Step 1 — Find the standard output per hour (standard time per unit = 20 seconds):

  • 1 hour = 60 × 60 = 3,600 seconds.
  • Standard output per hour = 3,600 ÷ 20 = 180 units per hour.

Step 2 — Find the piece rate per unit (normal rate per hour = Rs.1,800):

  • Piece rate = Normal rate per hour ÷ Standard units per hour = 1,800 ÷ 180 = Rs.10 per unit.

Step 3 — Earnings under straight piece-rate (Earnings = Units produced × Piece rate):
