A container has 180 L milk and X L water. When 10 L water is added, water becomes 14.001% of total. Find approximate resultant quantity of water.
- 29.3 liter
- 32.6 liter
- 24.8 liter
- 36.2 liter
Correct answer: 29.3 liter
Solution
(X+10)/(180+X+10)=0.14. (X+10)=0.14(190+X). X+10=26.6+0.14X. 0.86X=16.6. X≈19.3L. Resultant water=19.3+10≈29.3L.
