P is six times as large as Q
P is six times as large as Q. The percent that Q is less than P is (a) 83 1/3% (b) 70% (c) 63 1/3 (d) 50% SOLUTION 1: P is six times as large as Q Q is less than P by - Therefore 6P=Q Q = 6-1 = 5 smaller than P therefore 5/6 * 100 = 83 1/3 % option (a) SOLUTION 2: For easy understanding let the Q as 100 Than P is 6 times as large as Q , therefore 6 * 100 = 600 Now how much Q is less than P = 600-100 = 500 Q is 500 less than 600 therefore in percentage 500/600*100 5/6* 100 = 83 1/3% option (a) CLICK HERE FOR VIDEO SOLUTION
The difference of two numbers is 15% of their sum, the ratio of the larger number to the smaller number is
The difference of two numbers is 15% of their sum, the ratio of the larger number to the smaller number is (a)23:17 (b) 11:9 (c) 17:11 (d) 23:11 SOLUTION : Let the two number be x and y As per question, x -y = 15 % of ( x+y ) x-y=15/100 * ( x+y ) 100 * (x-y) = 15 * ( x+y ) x+y = 100 and x-y=15 , solving both equation x=115/2 y=85/2, ratio of larger to smaller is x/y= (115/2)/(85/2) = 23:17 option (a) CLICK HERE FOR VIDEO SOLUTION
