Question

Ram spends 30% of his salary on house rent, 30% of the rest he spends on his children's education and 24% of the rest salary he spends on clothes. After his expenditure, he is left with Rs. 2500. What is Ram's salary?

• A. 6713.2
• B. 20,000
• C. 10,000
• D. 15,000

Answer 1

The correct option is A 6713.2

Let total salary is Rs. x

$P[1+\frac{x}{100}][1+\frac{y}{100}][1+\frac{z}{100}]=2500$

$P[1-\frac{30}{100}][1-\frac{30}{100}][1-\frac{24}{100}]=2500$

[(-)ve sign because of spending]

$P\left[\frac{70}{100}\right]\left[\frac{70}{100}\right]\left[\frac{76}{100}\right]=2500$

P = Rs. 6713.21
