alleryएक टंकी सामान्यतः 6 घंटे में भरती है लेकिन एक रिसाव (लीक) के कारण इसे भरने में 8 घंटे लगते हैं। अकेला रिसाव पूरी भरी टंकी को कितने समय में खाली कर देगा?
A18 घंटे
B48 घंटे
C24 घंटे
D14 घंटे
Answer & Solution
Correct answer: C. 24 घंटे
रिसाव की दर = 1/6 - 1/8 = 1/24 प्रति घंटा है, अतः यह भरी टंकी को 24 घंटे में खाली कर देगा।
