Sushant spent 18% of his monthly salary on buying electronic goods and 32% of the monthly salary on repair work in his house: Out of the remaining amount he invested 42% in fixed deposits. If he was left with Rs.12,325, how much is his annual salary?

Let monthly salary = Rs. $$100x$$

Amount spent on buying electronic goods = $$\frac{18}{100} \times 100x = 18x$$

Amount spent on repair work = $$\frac{32}{100} \times 100x = 32x$$

Amount left = $$100x - 18x - 32x = 50x$$

Amount invested in fixed deposits = $$\frac{42}{100} \times 50x = 21x$$

=> Amount left = $$50x - 21x = 29x$$

Acc to ques,

=> $$29x = 12325$$

=> $$x = \frac{12325}{29} = 425$$

=> Monthly salary = 100 * 425 = Rs. 42,500

$$\therefore$$ Annual salary = 42500 * 12 = Rs. 5,10,000
