Coins of the Indian rupee 3, 5, 10, 20, 25, 50 (naya) paisa and one rupee. Since rupees retained their pre-decimal value, pre-decimal coins of one, half and quarter rupees remained in circulation after decimalisation. The word "naya" was dropped in 1964 and a new denomination, the 3 paisa, was introduced into circulation. A 20 paisa coin was minted in 1968. Neither of these coins gained much popularity. The 1, 2 and 3 paisa coins were phased out gradually in the 1970s. In 1982, a new 2 rupee coin was introduced experimentally to replace 2 rupee notes. The 2 rupee coin was not minted again
Decimal enough (for all "n" greater than some natural number "N"). If all "d" for "n" > "N" equal to 9 and the limit of the sequence formula_9 is the decimal fraction obtained by replacing the last digit that is not a 9, i.e.: "d", by "d" + 1, and replacing all subsequent 9s by 0s (see 0.999...). Any such decimal fraction, i.e., "d" = 0 for "n" > "N", may be converted to its equivalent infinite decimal expansion by replacing "d" by "d" − 1, and replacing all subsequent 0s by 9s (see 0.999...). In summary, every real number that
