Answer 1

Answer:

100ml x 15% mixed with 150ml so 150ml x 25%

then divideanswer to those twp (100ml x 15%) and (150ml x 25%)

so 5  (random number) divvidedby 6 (random number)

Answer 2

Explanation:

1gram = 1 ml

salt solution 1 =100×15/100

=15g

salt solution2 =150×25/100

=150/4

=37.4g

total water=(100-15) + (150-37.4)

total water=(100-15) + (150-37.4)=75+113.6

total water=(100-15) + (150-37.4)=75+113.6=188.6ml (for knowlege no need in ques.. to fing value of water)

total salt=15+37.4

=52.4g

percentage of salt in solution

salt percentage= (total salt/total solution)×100

=(52.4/250)×100

=524/25

=20.96%
