let the ages be 6x and 7x
6x+12/7x+12 = 12/13
13(6x+12) = 12(7x+12)
78x+156 = 84x+144
12=6x
x=2
6x=127x=14
Mathu's age = 12Meena's age = 14
Ratio : 6: 7Verification
12 years later
Mathu's age = 24Meena's age = 26
Ratio = 12:13
6x+12/7x+12 = 12/13
13(6x+12) = 12(7x+12)
78x+156 = 84x+144
12=6x
x=2
6x=127x=14
Mathu's age = 12Meena's age = 14
