Read this question in English
There is an order of 19000 quantity of a particular product from a customer. The firm produces 1000 quantity of that product per day out of which 5% are unfit for sale. In how many days will the order be completed?
(a) 18 · (b) 19 · (c) 20 · (d) 22
उत्तर और व्याख्या · explanation in English
Answer: (c) 20
Only 95% of each day's 1000 units can be sold, which is 950 units a day. The order of 19000 therefore takes 19000 ÷ 950 = 20 days.
- Usable output per day = 95% of 1000 = 950.
- Days needed = 19000 ÷ 950 = 20.
- Check: 20 × 950 = 19000.
Remember · Divide the order by the usable output per day, not the gross output.
