John purchased 24 chocolates for Rs.96. How many chocolates can be purchased for Rs.72?

|| Answer ||

John purchased 24 chocolates = Rs.96.

Chocolates can be purchased for Rs.72 = x

`(24)/(96) = (x)/(72)`

24:96 = x:72

Means = Extreams

96 × x = 24 × 72

`x = (24 * 72)/(96)`

( 12 × 2 = 24, 12 × 8 = 96 )

`x = (2 * 72)/(8)`

(8 × 1 = 8, 8 × 9 = 72)

`x = (2 * 9)/(1)`

`x = 2 * 9`

`x = 18`

Therefore, 18 chocolates can be purchased for Rs.72
