X can do a work in 6 days and Y can do same work in 8 days. With the help of Z, all three finished the work in 3 days. If they altogether got Rs. 2000 after completing the work, then Z gets :X एक कार्य को 6 दिन में पूर्ण कर सकता है और Y इसी कार्य को 8 दिन में पूर्ण कर सकता है। Z की सहायता से तीनों मिलकर इस कार्य को 3 दिन में पूर्ण कर देते हैं। यदि तीनों को कुल 2000 रुपये कार्य समाप्ति पर प्राप्त हुये, तो Z का भाग है :

Correct answer: B. Rs. 250250 रुपये
Explanation
One-day work: X = 1/6, Y = 1/8, all three = 1/3. So Z's one-day work = 1/3 − 1/6 − 1/8 = (8 − 4 − 3)/24 = 1/24. Z's share of the work = (1/24) ÷ (1/3) = 1/8, so Z gets 2000 × 1/8 = Rs. 250.एक दिन का कार्य: X = 1/6, Y = 1/8, तीनों = 1/3। अतः Z का एक दिन का कार्य = 1/3 − 1/6 − 1/8 = (8 − 4 − 3)/24 = 1/24। कुल कार्य में Z का भाग = (1/24) ÷ (1/3) = 1/8, इसलिए Z को मिलेंगे 2000 × 1/8 = 250 रुपये।More Mathematics & Numerical Ability questions
