Q. A solution contains 25% salt. If 8 liters of the solution is removed and replaced with water, what is the new concentration of salt in the solution?
A.
20%
B.
25%
C.
30%
D.
15%
Solution
Salt removed = 25% of 8L = 2L. New solution = 32L, new salt % = (25L / 32L) * 100 = 20%.
Q. A solution contains 40% sugar. If 5 liters of the solution is removed and replaced with water, what is the new percentage of sugar if the total volume remains the same?
Q. A train and a boat start from the same point and travel in opposite directions. If the train travels at 80 km/h and the boat at 20 km/h, how far apart will they be after 2 hours?
A.
200 km
B.
160 km
C.
140 km
D.
120 km
Solution
Distance covered by train = 80 km/h * 2 hours = 160 km. Distance covered by boat = 20 km/h * 2 hours = 40 km. Total distance apart = 160 km + 40 km = 200 km.
