there are two positive numbers.Each was increased by 30 and then by same percentage as it was increased the first time . after the second increase the value of each no. is 147 . find the difference between the two numbers.

63

The answer should be 0 because after increase the values of both the number is same. however, it may be solved as below: 130 % of (x+30) = 147 and 130% of (y +30) = 147 130 % of (x+30) = 130% of (y+30) so, x+30 = y +30 therefore, x = y Hence x - y = 0
