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.
