Question

Ramesh bought $x$ applies at Rs.$0.50$ each and $y$ kiwi fruit at Rs.$0.80$ each. He sold the apples at Rs.$0.85$ each and the kiwi fruit at Rs.$1.00$ each. Which of the following algebraic expressions correctly shows the profit earned by Ramesh?

• A. $35x+20y$
• B. $35xy$
• C. $20xy$
• D. $30x+15y$

Answer 1

The correct option is A $35x+20y$

Given parched cost of apple $=0.50$ Rs

And parched cost of kiwi $=0.80$ Rs

Then parched cost of apples $=0.50x$ Rs

And parched cost of kiwis $=0.80y$ Rs

Given sales cost of apple $=0.85$ Rs

And sales cost of kiwi $=1.00$ Rs

Then sales cost of x apples $=0.85x$ Rs

and sales cost of y kiwis $=1.00y$

So total parched cost of $x$ apples and $y$ kiwis $=0.50x+0.80y$ Rs

And total sales cost of $x$ apples and $y$ kiwis $=0.85x+1.00y$ Rs

So, profit $=(0.85x+1.00y)-(0.50x+0.80y)=0.85x+1.00y-0.50x-0.80y=0.35x+0.20y$

Then algebraic expression of profit $=35x+20y$
