Kindly, explain if anyone knows the solution.​

Answer 1

Answer:

Step-by-step explanation:

Let original amt be y

19 = 100/100 - 5/100 = 95/100 = 95%  ( because as it was 5% that was lost, what remains is 95%)

y * 95/100 = 19

y * 19/20 = 19

y = 19 / 19/20

y = 19 * 20/19

y = 20kg

Originally there was 20 kg oil in the tin

So amount lost was 20 * 5/100 = 1

20-1 = 19

Thus explained
