let the full capacity of drum be x then according to question
3x/4 - 15 = 7x/12
solving this equation we get
36x - 720 = 28x
36x - 28x = 720
8x = 720
x = 90
so barrel's capacity is 90 ltrs
3x/4 - 15 = 7x/12
solving this equation we get
36x - 720 = 28x
36x - 28x = 720
8x = 720
x = 90
so barrel's capacity is 90 ltrs
