Question
A factory produces 800 units of product A in 5 days. If
the production rate increases by 25% after 3 days, how many days will it take to produce a total of 1,600 units?Solution
Initial production rate = 800 units / 5 days = 160 units/day. Production in the first 3 days = 3 * 160 = 480 units. Remaining units = 1,600 - 480 = 1,120 units. Increased rate after 3 days = 160 * 1.25 = 200 units/day. Days to produce 1,120 units at 200 units/day = 1120 / 200 = 5.6 days. Total days = 3 + 5.6 = 8.6 days (approx). Correct answer: A) 8.6 days
