Suppose a consumer can afford to buy 8 units of good X and 10 units of good Y. She spends her entire income. The prices of two goods are ₹7 and ₹9 respectively. The consumer's income is ₹ ____________.

₹146

The correct answer is option (2) : ₹146

To determine the consumer's income, we need to calculate the total expenditure based on the prices and quantities of goods X and Y that she can afford.

Given:

• Price of good X = ₹7
• Price of good Y = ₹9
• Maximum units of good X = 8 units
• Maximum units of good Y = 10 units
• Total expenditure (income) = Price of X * Quantity of X + Price of Y * Quantity of Y

Calculate total expenditure:

$\text{Total expenditure}=(7\times 8)+(9\times 10)$

$\text{Total expenditure}=56+90$

$\text{Total expenditure}=146$
