Maya added 5 grams of salt into 20 grams of 50% salt solution. she made grams of % salt solution.

Consider the suggested option:
1) if in 20 gr. of 50% solution given, then pure salt in this mix is 0.5*20=10 gr., and pure water is 0.5*20=10 gr.
2) after Maya added 5 gr. pure salt is 10+5=15 gr. Total mass of mix is 15(pure salt)+10(pure water)=25 gr.
3) new solution is 15/25=0.6 or 60%.
25 gr. of 60% salt solution.

Is 8.50 an answer or no? ?
