A.
1:3
B.
1:2
C.
1:4
D.
1:5
Solution
Original mixture = 15 liters (A = 5, B = 10). After adding 30 liters of B, new B = 40. New ratio = 5:40 = 1:8.
Q. A mixture of two grades of rice contains 60% grade A and 40% grade B. If 10 kg of grade B rice is added, what will be the new percentage of grade A rice if the total weight becomes 30 kg?
A.
50%
B.
60%
C.
70%
D.
40%
Solution
Initial weight of grade A = 60% of 20 kg = 12 kg. New total = 30 kg, new percentage of grade A = (12/30) * 100 = 40%.
