Question

A mobile operator charges ₹ 0.15 per minute for local calls and ₹0.23 per minute for long distance calls. Which expression gives the total cost in rupees for "$x$" minutes of local calls and "$y$" minutes of long distance calls?

• A. ₹$\text{(}0.15x+0.23y)$
• B. ₹$\text{(}0.15x-0.23y)$
• C. ₹ $\text{0}.38(x+y)$
• D. ₹ $\text{0}.28xy$

Answer 1

The correct option is A ₹$\text{(}0.15x+0.23y)$

Given, the charges for local and long distance calls are ₹0.15 per minute and ₹0.23 per minute respectively.

Total minutes of local call = $x$
Total minutes of long distance call = $y$

$\therefore$ The required algebraic expression is ₹ $\text{(}0.15x+0.23y)$
