Solution

Dear Student

Thank you for using chegg !!

Let x be Julio allowance in the month

Now 1/10 of Julio allowance is spent on markers

Rest allowance remaining

X - x/10 = 0.9 x

Next given 2/5 th I.e. 0.4x allowance is spent on books

Now allowance remaining

0.9x - 0.4x =0.5x

In fractions 1/2 of weekly allowance is remaining

So correct option is A.
