If a vessel gets filled by 15 glasses of milk where capacity of each glass is 1.5 L, how many glasses are required to fill the same vessel if the capacity of each glass is 0.5 L?

Correct option is B

Given:
Capacity of 1st glass = 1.5 L
 Number of glasses = 15
Capacity of 2nd glass = 0.5 L
 Formula Used:
Total volume of the vessel remains the same.
 Total Volume = Number of Glasses × Capacity per Glass
Solution:
Total Volume = 15 × 1.5 = 22.5 L
Required number of glasses = $$\frac {22.5}{ 0.5}$$​ = 45
