Question
A number is such that when it is multiplied by 4, it
gives another number which is as much above from 180 as the original number (itself) is below 180. The average of the original number and the resultant number is:Solution
Let the number be x. According to question, => 180 – x = 4x – 180 => x = 72 So, 4x = 288 Therefore the average of = (72 + 288)/2 = 180
