Question

Ranjana used 1/2 litre of oil to dry puris and 3/4 litre of oil for cooking all other food items. How much oil was left after complete cooking if she had a container of 15 litre oil??​

Answer 1

Answer:

=>> 55/4 litre  oil is left after cooking.

Step-by-step explanation:

Let the amount of oil left in the container be x litre

Amount of oil used to dry puris = 1/2 litre

Amount of oil used for cooking other food items = 3/4 litre

The total amount of oil she had in container = 15 litre

=>                                               $x + \frac{1}{2} + \frac{3}{4} = 15$

=>                                                  $x + \frac{2+3}{4} = 15$

=>                                                      $x + \frac{5}{4} = 15$

=>                                                             $x = 15 - \frac{5}{4}$

=>                                                             $x = \frac{60 - 5}{4}$

=>                                                             $x = \frac{55}{4}$

Hence, 55/4 litre  oil is left after cooking.
