यदि A, B और C किसी काम को 2, 4 ,8 दिन मैं करे तो तीनों मिलकर कितने दिन मै करेंगे |
|
Answer» Answer: no need; Step-by-step explanation: as they have done the work ALREADY, then why would they do the same work again? but if we think mathematically, then it would take approx three DAYS because A is the fastest and B is a little slow so if both do the work, then B would do the work HALF while A would complete the whole work hence 3 days. C not included because it takes too long, but till then the work would already have been COMPLETED. |
