Question
A number is such that when it is multiplied by 3, it
gives another number which is as much above from 270 as the original number (itself) is below 270. The average of the original number and the resultant number is:Solution
Let the number be x. According to question, => 270 – x = 3x – 270 => x = 135 So, 3x = 405 Therefore the average of = (135 + 405)/2 = 270
