Twenty-four workers complete 1/4 in 10 days, so the remaining 3/4 needs 30 equivalent days at the same workforce.
Only 20 days remain, requiring 36 workers, so 12 extra are needed.

Twice the efficiency means twice the daily work rate.
Therefore, A takes half of 18 days, which is 9 days.

In four days, each works twice.
Completed work is 2/15 + 2/20 = 4/30 + 3/30 = 7/30.

Profit is shared in the ratio of investments, 3:5.
B receives 5/8 of Rs. 16,000 = Rs. 10,000.

Capital-time products are 40,000 × 12 and 60,000 × 8.
Both equal 480,000, so the ratio is 1:1.

A's capital-time is 2 × 6 + 4 × 6 = 36 units.
B's is 3 × 12 = 36 units, so profits are equal.

A 20% profit gives a selling price of Rs. 960.
Since this is 80% of marked price, marked price = 960/0.8 = Rs. 1,200.

He charges for 1,000 grams but supplies only 900 grams.
Gain percentage is 100/900 × 100 = 11 1/9%.

The selling price is 80% of the marked price.
Thus, marked price = 960 ÷ 0.80 = Rs. 1,200.

Sales tax is 12% of Rs. 5,000, or Rs. 600.
The total payable amount is Rs. 5,600.

Commission is 6% of total sales.
Thus, 0.06 × 250,000 = Rs. 15,000.

The taxed price is 115% of the original price.
So the original is 2,300 ÷ 1.15 = Rs. 2,000.
