Explanation

Initial employees = 9x, wages = 14y. Initial bill = 126xy = 189000. xy = 1500. New employees = 8x, wages = 15y. New bill = 120xy = 120 * 1500 = 180000. Decrease = 189000 - 180000 = 9000.

AI explanation

The new wage bill is calculated by multiplying the old wage bill by the ratio of the new number of employees to the old number of employees and the ratio of the new wage to the old wage. Using the given ratios, the new wage bill is Rs. 1,89,000 multiplied by (8 / 9) and then by (15 / 14), resulting in Rs. 1,80,000. The wage bill decreases by Rs. 1,89,000 minus Rs. 1,80,000, which is Rs. 9,000.
