Answer 2

1760

Note: She used an EQUAL amount of oil each day.

“At the end of the 4th day, she had 880 ml of oil left. At the end of the 6th day, she had half the bottle of oil left.”

From these statements, we know that half of the 880 ml finished in 2 days.

This means she had 440 ml of oil at the end of the 6th day.

Since there are 4 days left, multiply 440 × 2, and we get:

440 × 2 = 880

Now add 880 ml that was already left and from the above calculation, we get:

880 + 880 = 1760

Hope this helps :)
