Question

a drum of kerosene oil is 3 upon 4 full when 15 liters drawn from it it is 7/12 full find its total capicity​

Answer 1

Answer:

Total capacity of the tank is 90 litres.

Step-by-step explanation:

If a drum of Kerosene is $\frac{7}{12} x$ of its total capacity full when 15 liters of kerosene is taken out and if the tank has $\frac{3}{4} x$ of its capacity, it can be represented using the following equation.

$\frac{7}{12}x + 15 = \frac{3}{4}x$

= $\frac{7}{12}x - \frac{3}{4}x = -15$

= $\frac{7}{12}x - \frac{9}{12}x = -15$

= $\frac{-2}{12}x = -15$

= $x = -15$ × $\frac{-12}{2}$

= $x = \frac{180}{2}$

= $x = 90$ liters.
