Solution

Let's solve this step by step:

  1. Let's assume Mr. Rama's income is X.

  2. He spends 30% of his income on food, which means he is left with 70% of his income. So, the remaining income is 0.70X.

  3. He spends 20% of the remaining income on books. So, he is left with 80% of his remaining income, which is 0.80 * 0.70X = 0.56X.

  4. He spends 10% of the remaining income on entertainment. So, he is left with 90% of his remaining income, which is 0.90 * 0.56X = 0.504X.

  5. According to the problem, the remaining amount after all the expenses, which is 0.504X, is Rs. 10,080.

  6. So, we can set up the equation 0.504X = 10,080.

  7. To solve for X, we divide both sides of the equation by 0.504.

    X = 10,080 / 0.504 = Rs. 20,000.

So, Mr. Rama's income is Rs. 20,000.
