If a chemical solution contains 8% of base, if there is 15ml of base,what is the volume of solution?

(A) 135.5ml

(B) 187.5ml

(C) 175.5ml

(D) 220.5 ml

Answer: (B) 187.5ml

Solution:

8ml base in solution = 100ml

1ml base in solution = 8/ 100 = 12.5ml

15ml base in solution = 12.5 × 15 = 187.5ml.

so answer is = (B) 187.5ml
