Question
A number is such that when it is multiplied by 5, it
gives another number which is as much above from 210 as the original number (itself) is below 210. The average of the original number and the resultant number is:Solution
Let the number be x. According to question, => 210 – x = 5x – 210 => x = 70 So, 5x = 350 Therefore, the average of = (70 + 350)/2 = 210
