Answers
Answer:
One person's initial income is 7200 rupees. His pay went up by 20%, while the price of commodities went up by 30%, and his savings went down by 6%. The increased cost is 9550.4 rupees.
Explanation:
To determine the increased cost, we need to calculate the person's net income and compare it to the initial income.
First, we can calculate the person's new salary after a 20% increase:
New Salary = 7200 + (20/100)*7200
New Salary = 7200 + 1440
New Salary = 8640 rupees
Next, we can calculate the increase in the cost of raising commodities after a 30% increase:
Increased cost of raising commodities = (30/100)*7200
The increased cost of raising commodities = 2160 rupees
We also need to calculate the person's new savings after a 6% decrease:
New Savings = (94/100)*8640
New Savings = 8110.4 rupees
Now, we can calculate the person's new income by adding the new salary and new savings:
New Income = New Salary + New Savings
New Income = 8640 + 8110.4
New Income = 16750.4 rupees
The increased cost can be calculated by finding the difference between the new income and the initial income:
Increased cost = New Income - Initial Income
Increased cost = 16750.4 - 7200
Increased cost = 9550.4 rupees
