Question
Nikhil spent 5% of his monthly income on his children's education, invested 14% in shares, deposited 3% in a bank and used 40% for his daily expenses. He was left with a balance of Rs. 19,000. What was his income that month?
Solution
Let the monthly income be Rs x = `100/100x`
Money spent on children's education = `5% "of" x = 5/100x`
Money spent on shares = `14% "of" x = 14/100x`
Money deposited in banks = `3% "of" x = 3/100x`
Money spent on daily expenses = `40% "of" x = 40/100x`
Savings = `"Rs" 19,000`
`5/100x + 14/100x + 3/100x + 40/100x + 19000 = 100/100x`
⇒ `62/100x + 19000 = 100/100x`
⇒ `100/100x-62/100x = 19000`
⇒ `38/100x = 19000`
⇒ `x = 19000 xx 100/38`
⇒ `x = 50000`
