Question

In bag containing red , green and pink token,the ratio of red and green token was 12:35 while the ratio of pink and red token 25:18.what is the ratio green and pink token.

Answer 1

let, r , g and p are red , green and pink token .

now , according to question,

r : g = 12 : 35

r / g = 12 / 35 --------------------------eq.(1)

given ,

p : r = 25 : 18

p / r = 25/ 18 --------------––----------eq.(2)

multiply eq.(2) and (1)

( p / r ) × ( r / g ) =( 25 / 18 ) × ( 12 / 35 )

p / g = 5 × 2 / 3 × 7

p / g = 10 / 21

p : g = 10 : 21

then , g : p = 21 : 10

hence the ratio of green and pink token = 21 : 10
