Answer 1

Answer:

current age of Smita and her mother is in 3:7

so S:M=3:7

at the time of birth Smita's age=0 and her mother age is 28

so lets say after 21 years smita's age=21 and her mother age=49

so ratio 21:49=(7×3):(7×7)=3:7

so current age of Smita=21 and her mother=49

Answer 2

Answer:

smita:21yrs and mother:49 yrs
