Final answer:

Kareem's total salary is Rs 12,000.

Step-by-step explanation:

To find Kareem's total salary, we need to work backwards. Let's start by setting up an equation:

Let S be Kareem's salary.

After donating 10% of his salary to charity, Kareem has 90% of his salary remaining. So, he has 0.9S left.

Next, Kareem spent 30% of the remaining amount, which means he has 70% (100% - 30%) of the remaining amount left: 0.7 * 0.9S = 0.63S.

We are told that Kareem has Rs 7560 left, so we can set up the equation:

0.63S = 7560

Solving for S, we divide both sides of the equation by 0.63:

S = 7560 / 0.63 = 12,000

Therefore, Kareem's total salary is Rs 12,000.
