Answer» Correct Answer - Option 1 : 20,000

Given:

Rahul gives 20% of some amount to his wife.

And, 20% of the remaining amount to charity

Remaining Amount = Rs. 12,800

Calculation:

Let be total amount of Rahul be 100 unit

Rahul gives his wife = 100 unit - 20 unit

⇒ Then remaining amount is 80 unit

Then he gives 20% in charity = 80 unit × 80%

⇒ Remaining amount is 64 unit 

Giving,

⇒ 64 unit = 12800

⇒ 1 unit = 200

⇒ Total monthly income = 200 × 100

∴ Rahul monthly income is 20,000.
