Final answer:
The number of pads remaining in stock after the stock clerk issued pads to three divisions is 65.
Step-by-step explanation:
To solve this problem, we need to find the fraction of pads that the stock clerk issued to each division and subtract it from the initial number of pads. The stock clerk issued 3/8 to Division X, which is (3/8) * 600 = 225 pads. He issued 4 to Division Y and 1/6 to Division Z, which is (4 + 1/6) * 600 = 310 pads. The total number of pads issued is 225 + 310 = 535 pads. To find the number of pads remaining in stock, we subtract the issued pads from the initial number of pads: 600 - 535 = 65 pads.
