Punto:- Number:- 1825=7, paid 2.5K as this is not a fancy ( but missed this 1789=7, due to my fault & overlook as this was without pay inside the series). Linea:- 7333- Fancy but lucky with only paying 2.5K. ( why fancy:- First digit is 7, rest three are same digit, 7+3+3+3=16=1+6=7 same as first digit, same logic for other nuber as 1333, 2333, 3333, 4333, 5333, 6333, 7333, 8333,& 9333) I was looking for 7576=7, but N.Kiran told me to check 7333. Later I discovered above logic. Thanks N.Kiran ( your number also falls under same logic). BTW, I am little conservative to select 7 always .
