Answer:

He has been saying money for 43 weeks.

Step-by-step explanation:

Given,Abu decided to deposite 35 rupees in the bank each week.

Therefore in 1 week ,he can deposit 35 rupees.

Now it is also given that he has 1505 rupees in his account now.

So,total amount of money in his account 1505 rupees. By Unitary method,we can solve this question.

But now question is what is use of Unitary method?

By one example we can understand this concept.

Let cost of 5 apple is 50 rupees

then by Unitary method cost of 1 apple is $\frac{50}{5} = 10 \: rupees$

And cost of 20 apple is $(20 \times 10) = 200 \: rupees$

Here he can deposit 35 rupees in 1 week

and by Unitary method,he can deposit 1 rupee in $\frac{1}{35} \: week$

and he can deposit 1505 rupees in

$\frac{1505}{35} \: = \frac{215}{5} \\ = 43 \: weeks$
