Ten gallons of a 25% salt solution are to be obtained by mixing solutions that are 13% salt and 33% salt respectively. How many gallons of each are needed?

salt + salt = salt

0.13x +3.3-0.33x =2.5

-0.20x=-0.8

x= 4 gallons (amt of 13% solution to be mixed)

10-x= 6 gallons (amt of 33% solution to be mixed)

Step-by-step explanation:

62.5 paisa

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5
