subtracted from all the odd digits of the number 3984525783, after that all the digits are arranged in ascending order from right to left, then, what will be the absolute difference between the sum of digits of first half from the left end after the rearrangement and the sum of digits of second half from the right end after the rearrangement?Solution
3         9         8         4         5         2         5         7         8         3         1         7         9         5         3         3         3         5         9         1         9         9         7         5         5         3         3         3         1         1         Sum of digits of first half from the left end = 9 + 9 + 7 + 5 + 5 = 35. Sum of digits of second half from the right end = 3 + 3 + 3 + 1 + 1 = 11. Require difference = 35 – 11 = 24.
