Given that 15% of X’s income = 20% of Y’s income = 30% of Z’s income. The sum of their incomes is Rs 9,000. If Y spends Rs 2,200 from his income, then Y’s savings is:
Show answer & explanation
Correct answer: A
Explanation
The Correct answer is option 1 i.e. Rs 800.
15% of X’s income = 20% of Y’s income = 30% of Z’s income
The ratio of the income (X : Y : Z) = 4 : 3 : 2
Let the income of X, Y, and Z be 4x, 3x, and 2x.
According to the question;
⇒ 4x + 3x + 2x = 9000
⇒ 9x = 9000
⇒ x = 1000
Income of X = 4x = 4000
Income of Y = 3x = 3000
Income of Z = 2x = 2000
We know that,
Income = Expenditure - Savings
Savings of Y = Income of Y - Expenditure of Y
Savings of Y = 3000 - 2200
Savings of Y = Rs.800
