Question

an ice cream vendor has vanilla and chocolate ice cream in the ratio of 4:9. If there are 100 vanilla ice-creams, find the number of chocolate icecreams

Answer 1

225

Explanation:

Let the number of vanilla ice cream be x and number of chocolate ice cream be y.

Given ratio of vanilla and chocolate ice cream = 4:9

Mathematically,x:y=4:9

• x/y = 4/9
• 4y = 9x

Given the number of vanilla ice cream: 100 = x

Putting the value of x in the above equation,

• 4y = 9*100
• y = 9*100/4
• y = 9*25 = 225

Hence the number of chocolate ice creams = 225
