Two numbers are such that their sum, difference and product are in the ratio 11 : 1 : 90. Find the numbers.

मान लीजिए संख्याएँ a, b हैं। (a+b)/(a-b) = 11/1 => 12b = 10a => a/b = 6/5। मान लीजिए a=6k, b=5k। गुणनफल ab = 30k²। (a+b)/ab = 11/90 => 11k / 30k² = 11/90 => 1/30k = 1/90 => k=3। संख्याएँ: 18, 15।
