A man spend 20% of his monthly salary on his children's education and 50% of his salary on food and transport. After Paying the rent of Rs.1000, he is left with Rs.2000. What is his monthly salary?
Correct Answer: 10000
Let his monthly salary be 'P'
20% on children's education = 20P100 = P5
50% on food and transport = 50P100 = P2
1000 on rent
=> P - P5 - P2 - 1000 = 2000=> 3P = 30000=> P = 10000
Therefore, his monthly salary = Rs. 10,000
