Consider the numbers 1, 2, 3, and 5. If the same number is added to each of the numbers, it is found that the ratio of the first new number to the second new number is the same as the ratio of the thurd new number to the fourth. Find the number. Solution Let the number be \'x\' Then, (1+x)/(2+x) = (3+x)/(5+x) or, (1+x)(5+x) = (3+x)(2+x) or, 5 + x2 + 6x = x2 + 5x + 6 or, x = 1 ANS..
