20+20xP%=60-60xP% =>80xP%=40 =>P=50 So P=50% of 70 is 35

20 + x = 60 - y; x + y = 40 x=0.2P and y = 0.6P So, 0.8P = 40 P=50. 50%of 70 is 35.

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

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
