A) 27, 9, 21 | B) 9, 21, 27 |

C) 21, 27, 9 | D) 9, 27, 21 |

Explanation:

Let Anushka age = X

Charu latha 12 yrs older than Anushka so Charu latha age = x+12

Kajal is thrice as old as Anushka so Kajal age = 3x

The ages of Anushka, Kajal and Charu latha together are 57 years

i.e x + (x+12) + 3x = 57

=> 5x = 45

:- x = 9

Anushka age = 9

Kajal age = 3x = 27

Charu latha age = x+12 = 21
