Answer» In vessel, 3 PARTS are water, and 5 parts syrup. So TOTAL it is divided in 8 parts. So, water = 3/8 and syrup = 5/8 To make them equal, 1/2 = 4/8 of both water and syrup, suppose we replace x PART of liquid by water then, and then both must be same. water in drawn part : 3x/8 and syrup : 5x/8 After replacement : water = water before replacement - 3x/8(removed) + x(REPLACED) syrup=syrup before replacement - 5x/8(removed) To make them equal : water before replacement + 5x/8 = syrup before replacement - 5x/8 So, syrup before replacement - water before replacement = 10x/8 = 5x/4 So, 5/8 part - 3/8 part = 5x/4 So, 1/4 part = 5x/4 So, x = 1/5 part Here is your answer mate please follow me please mark it as brainlist please thanks my all answers |
