Question

9.) The ratio of Reema's age to Sadhana's age His 6:7. After 12 years the ratio of their ages 1 will be 12: 13. Find their present ages.​

Answer 1

Answer:

let reem's age = 6x

Sadhana's age =7x

given after 12 years

ratio of their ages=12/13

6x+12/7x+12=12/13 cross multiply

(6x+12)13=12(7x+12)

78x+156=84x+144

156-144=84x-78x

12=6x

x=2

there present ages = Reem= 2*6=12

                               Sadhana=2*7=14
