Step-by-step explanation:

After reading the statement, the reminder is 9/10 of the weekly allowance on Wednesday. The proportion of allowance left at the end of Wednesday is:

The percentage is:

60% of his total allowance.

Step-by-step explanation:

If Rahul spent 10% on Monday, the reminder after Monday will 100% (the total) - 10% = 90%

Then, on Wednesday, he spent 1/3 of the reminder, that is, 1/3 of 90%, so the total he spent on Wednesday is (1/3) * 90/100 = 30/100 = 30%

If he spent 30%, now he has 90% - 30% = 60% of his total allowance.

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
