Mary and Ann age will be 43 and Helen will be of 48.
As no of candles has blow is 1+2+3+4.......n that is n(n+1) /2 and after calculation it will be 43.
For Ann and Helen if their age is n and n+5 then no of candles blow will be (1+2+3+4..... n) +(1+2+3+4..... n+5) so after calculation value of n will be 38 so n+5= 43
