Two figures are 20 percent and 50% greater than a third number, respectively. The following is the ratio of the two numbers:
A. 2 : 5 B. 3 : 5 C. 4 : 5 D. 6 : 7
Explanation: Let x be the third number.The first value is thus equal to 120 percent of x = 120x/100 = 6x/5.150 percent of x = 150x/100 = 3x/2 is the second number.The ratio of the first two integers is 6x/5:3x/2, which is 12x/15x = 4:5.
