Question

An ice cream Store with 12 different flavors sells 1 and 2 scoop ice cream cones. A boy sitting outside the store Counted 11 people with ice cream cones and a total of 15 scoops of ice cream how many one Scoop cones were sold

Answer 1

7 cones of 1 scoop ice cream were sold.

Explanation:

A total of 15 scoops were sold .

Let x be the number of 2 scoop ice cream and y be the number of 1 scoop ice cream

Then

15= 2x+ y---- eq. 1

There were 11 cones sold.

and x+ y = 11--- eq.2

11-x= y

15= 2x+ y

Putting value of y from eq.2 in eq. 1

15= 2x + 11-x

15= x+11

15- 11= x

x= 4

There will be 2*4=8 scoops for 4 cones

ie 4 cones of two scoops ice creams will be sold.

11- 4= 7 cones

and 7 scoops for 7 cones
