Solution: 20(100+p)/100 = 60(100-p)/100 100+p = 3(100-p) p= 200/4=50 p% of 70 = 50% of 70 =(50/100) x 70 =35

Comments Increasing 20 by P% => x=20+20.P/100 Decreasing 60 by P% => y=60-60.P/100 Acoording to the question, x=y => 20+20.P/100=60-60.P/100 Solving we get P=50 So, P% of 70=50% of 70=35 So, answer is 35

POST YOUR REQUIREMENT NOWAnswer is 35 The approach should be use the data given in the problem to form an equation. 20 + P% of 20=60 - P% of 60=> 20 + (P/100) x 20=60 - (P/100) x 60 solving this equation by shifting P to one side we get=> 80P/100 = 40=> P = 50 Now as P=50, P% of 70 implies 50% of 70 = 35

Comments Increasing 20 by P percent, we will get 20(1+(P/100)), and decreasing 60 by P percent, we will get 60(1-(P/100)). Equating the two expressions, we get P = 50 percent. 50 percent of 70 will be 70 X (50/100) = 35

Comments 20 + 20P/100 = 60 - 60P/100: 80P/100 = 40: P = 50 So 50% of 70 = 35

Comments 50% of 70 is 35 as 20+50%of20=60-50%of60 so 50% of 70 is 35.
