Insert commas suitably and write the names according to Indian System of Numeration:
(a) 87595762 (b) 8546283 (c) 99900046 (d) 98432701
According to the Indian Numeral system each digit has different value according to their place.
For example – 225
2 is used twice but it has different value in both the places, first 2 is in hundreds and second 2 represents the tens.
(a) 8, 75,95,762 = Eight crore seventy five lakh ninety five thousand seven hundred sixty two.
Let’s simplify it,
= 8, 0000,000 + 7, 000,000 + 5, 00,000 + 90,000 + 5, 000 + 700 + 60 + 2
= 8, 0000,000 + 7, 000,000 + 5, 00,000 + 90,000 + 5, 000 + 700 + sixty two
= 8, 0000,000 + 7, 000,000 + 5, 00,000 + 90,000 + 5, 000 + seven hundred sixty two
= 8, 0000,000 + 7, 000,000 + 5, 00,000 + 90,000 + five thousand seven hundred sixty-two
= 8, 0000,000 + 7, 000,000 + 5, 00,000 + ninty five thousand seven hundred sixty two
= 8, 0000,000 + 7, 000,000 + five lakh ninety five thousand seven hundred sixty two
= 8, 0000,000 + seventy five lakh ninety five thousand seven hundred sixty two
= Eight crore seventy five lakh ninety five thousand seven hundred sixty two
(b) 85,46,283
By simplifying it we get,
= 8, 000,000 + 5, 00,000 + 40, 000 + 6,000 + 200 + 80 + 3
= 8, 000,000 + 5, 00,000 + 40, 000 + 6,000 + 200 + 83
= 8, 000,000 + 5, 00,000 + 40, 000 + 6,000 + 283
= 8, 000,000 + 5, 00,000 + 40, 000 + 6,283
= 8, 000,000 + 5, 00,000 + 46,283
= 8, 000,000 + 5, 46,283
= 85, 46,283
Therefore 85,46,283
= Eight- five lakh forty six thousand two hundred eighty three
(c) 9,99,00,046
By simplifying it we get,
= 9, 00,00,000 + 9, 000,000 + 9, 00,000 + 0,000 + 000 + 46
= 9, 00,00,000 + 9, 000,000 + 9, 00,046
= 9, 00,00,000 + 99,00,046
= 9,99,00,046
Therefore, 9,99,00,046 = nine crore ninty nine lakh forty six
(d) 9, 84,32,701
By simplifying it we get,
= 9, 00,00,000 + 80,00,000 + 4,00,000 + 30,000 + 2,000 + 700 + 00 + 1
= 9, 00,00,000 + 80,00,000 + 4,00,000 + 30,000 + 2,000 + 701
= 9, 00,00,000 + 80,00,000 + 4,00,000 + 30,000 + 2,701
= 9, 00,00,000 + 80,00,000 + 4,00,000 + 32,701
= 9, 00,00,000 + 80,00,000 + 4,32,701
= 9, 00,00,000 + 84,32,701
= 9, 84,32,701
Therefore, 9, 84,32,701 = nine crore eighty four lakh thirty two thousand seven hundred one.
