A chemist mixes two solutions A and B in the ratio 3:5. If solution A constitutes 60 litres, how many litres of solution A and B?

180

150

100

120

To find the amount of solution A and B:

Let the amount of solution A be 60 liters.

The ratio of A to B is 3:5.

Therefore, if A is 60 liters, then B is 5/3 × 60 =100 liters.

So, the solutions are 60 liters of A and 100 liters of B.
