Answer:
225 rs
Step-by-step explanation:
cost of 1 pen = 20 rs
total cost of 4 pens = 20×4= 80 rs
cost of 1 pencil = 5 rs
total cost of 5 pencils = 5×5 = 25 rs
cost of 1 box = 60 rs
total cost of 2 boxes = 60×2 = 120 rs
Total= 80+25+120 = 225 rs
It's 42, here's a quick trick to do this, so we know there's 7 movies, and to find the combination we know we can't choose 2 of the same movie, so to make this part easier , in your head take one movie from the stack out of the stack now there's 6 movies. It's now just the "plug and play" step , (7)*(6)=(42)
I'm sorry If this is to long of an explanation, but I hope that this helps you understand on how to do this problem. Have a nice day :)
