Using effective tax rate to compute tax saving

I’m having trouble understanding the way profit is adjusted, after it is determined that COGS has increased by 194 million SEK during the year.

31 December (Swedish krona in millions) 2017
Profit (Net income) 21,283
Increase (reduction) in cost of sales (194)
Taxes (tax reduction) on operating profit* 49
Profit (without allowance) 21,138
  • Given the effective tax rate of 25%, taxes (tax reductions) on the operating profit are assumed to be 49 (194 × 25%) for 2017.
