A,B and C donate 8%,7% and 9%, of their salaries respectively to a charitable trust. The salaries of A and B are the same and the difference between their donations is ₹ 259. The total donation of A and B is ₹1,185 more than that of C. The total donation of A and C is what percentage of the total salaries of A,B and C? (Correct to one decimal place) A, B तथा C अपने वेतन का क्रमशः 8%, 7% तथा 9% भाग एक पुण्यार्थ ट्रस्ट में दान कर देते हैं| & और 8 के वेतन समान हैं तथा उनके दान में 259 रुपये का अंतर है | A और B का कुल दान C के दान से 1,185 रुपये अधिक है | A और C का कुल दान A, B तथा C के कुल वेतन का कितना प्रतिशत है ?

A, B and C started a business. Thrice the investment of A is equal to twice the investment of B and also equal to four times the investment of C. If C’s share out of the total profit is Rs. 4,863,then the share of A in the profit is: A, B और C ने एक व्यवसाय की शुरुआत की | A के निवेश का तिगुना B के निवेश के दोगुने तथा C के निवेश के चार गुना के बराबर है | यदि कुल लाभ में C का हिस्सा 4863 रुपये है, तो इस लाभ में A का हिस्सा ज्ञात करें |
