Assuming 18cm is the height (depth) then you have just 3cm more to fill to top.

Answer:

25%

Step-by-step explanation:

Apparently, we're to assume that anything not spent is saved.

Let Hideo's income be 1. Then Akira's income is 5/8. Akira's expenses are 60% = 3/5 of that value, so ...

Akira's expenses = (3/5)(5/8) = 3/8 . . . . . of Hideo's income

Hideo's expenses are twice this amount, so ...

Hideo's expenses = (2)(3/8) = 3/4 . . . . . of Hideo's income

That means Hideo saves 1 -3/4 = 1/4 = 25/100 = 25% of his income.

Hideo saves 25% of his income.
