The targeted weekly output of a manufacturing unit employing 20 workers is 400 pieces. The group is entitled to earn an incentive @ 10% on the aggregate of wages based on basic piece rate plus deamess allowance (which is Rs. 120 per week) upon achievement of a minimum of 80% of the output target. This incentive rate is increased by 2.5% flat for every 10% increase in achievement of targets up to a maximum of 10% at the level of 120% of the output target in the following manner:

Output Target	Incentive rate
80%-90% 90%-100% 100%-110% 110%-120% 120% and above	10% 12.5% 15% 17.5% 20%

During the four weeks in February, the actual output achieved by the workers are 383 pieces, 442 pieces, 350 pieces and 318 pieces respectively. The average basic piece rate is Rs. 5. Compute the amount of incentive earned by the group during each of the four weeks.
