a) Simplify them and find You bought 3 gel pens at Rs 25 each, 6 pencils at Rs 10 each and 2 boxes at Rs 80 each. If you gave a Rs 500 note to the shopkeeper, what changes did the shopkeeper return you? 1)

Here, given that [tex]3[/tex] gel pens are bought at Rs [tex]25[/tex] each. So, the cost of these [tex]3[/tex] gel pens is [tex]25\times 3=\text{Rs}\hspace{1mm}75[/tex].

Also, [tex]6[/tex] pencils are bought at Rs [tex]10[/tex] each. So, the cost of these [tex]6[/tex] pencils is [tex]10\times 6=\text{Rs}\hspace{1mm}60[/tex].

Also, given that [tex]2[/tex] boxes are bought at Rs [tex]80[/tex] each. So, the cost of these [tex]2[/tex] boxes is [tex]80\times 2=\text{Rs}\hspace{1mm}160[/tex].

Thus, the total cost of all the products bought is [tex]75+60+160=\text{Rs}\hspace{1mm}295[/tex].

So, if Rs [tex]500[/tex] were given to the shopkeeper, then he should have return [tex]500-295=\text{Rs}\hspace{1mm}205[/tex] in changes.

Therefore, after calculating the total cost, we have obtained that the shopkeeper returned Rs [tex]205[/tex] in changes.
