The table gives the profits (in rupees lakh) earned by five retail stores A to E during the years 2018 to 2023. Note that Profit equals Income minus Investment, and profit percent means profit as a percentage of investment. The specific profit figures needed are stated within each question below. Based on the data, answer the questions that follow.
In 2021, the owner of store C invests 9 lakh and earns a profit of 21 lakh, and store D earns a profit of 9 lakh. What should be the investment of store D in 2021 to get an income which is double that of store C?
The investment of store D should be 51 lakh, so that is the answer.
Store C invests 9 lakh and earns a profit of 21 lakh in 2021.
So the income of store C is 9 plus 21, which is 30 lakh.
Store D's income should be double that, which is 60 lakh.
Store D earns a profit of 9 lakh, and income equals profit plus investment.
So the investment of store D is 60 minus 9, which is 51 lakh.
