(a) 87595762 (b) 8546283 (c) 99900046 (d) 98432701

Answer :

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 a 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.
