उत्तर और व्याख्या · explanation in English
Answer: (c) प्रश्न का उत्तर, दोनों कथनों का एक-साथ प्रयोग कर दिया जा सकता है, किन्तु अकेले किसी भी एक कथन का प्रयोग कर नहीं दिया जा सकता है
Download time = size ÷ transfer rate. Statement I gives only the size and Statement II only the rate; together they fix the time.
- Time = size of the software ÷ transfer rate.
- Statement I gives the size (12 megabytes) but no rate, so it is not sufficient.
- Statement II gives the rate (2.4 kilobytes per second) but no size, so it is not sufficient.
- Together: 12 megabytes = 12,000 kilobytes (taking 1 MB = 1000 KB), so time = 12,000 ÷ 2.4 = 5,000 seconds; with 1 MB = 1024 KB it is 5,120 seconds. Either way the time is fixed.
Remember · In data sufficiency, write the formula first and tick off which statement supplies each quantity.
