Quantity I: Let the income of Yash be x. Rohit’s income = 52000 - x New income of Rohit = New income of Yash + 2200 Yash’s new income = x * 125/100 Rohit’s new income = (52000 – x)*115/100 (52000 – x)* (115/100) = x * (125/100) + 2200 => (5980000 – 115)/100 = (125/100) + 2200 => (5980000 – 115x) = (125x + 220000) => 5980000 – 220000 = 115x + 125x => 5760000 = 240 Yash’s income X = (5760000 /240) = 24000 Rohit’s income = 52000 – x = 28000 New Income of Rohit = 28000*(115/100) = Rs. 32200 Quantity II: 16D/100 = 20E/100 So, 4D = 5E 20E/100 = 25F/100 4E = 5F E = (5 28000)/4 = 35000 4D = 5E = (5
35000)/4 = Rs. 43750 Quantity I < Quantity II
