Q.1 Fill in the blanks:
(a) 1 lakh = ………………….. ten thousand.
(b) 1 million = ………….. hundred thousand.
(c) 1 crore = ………………… ten lakh.
(d) 1 crore = …………………. million.
(e) 1 million = …………………. lakh.
(a) 1 lakh = ….10… ten thousand
Solution: 1:-
ten thousand = 10,000
1 lakh = 100000 = 10 × 10,000
= 10 ten thousand
So, 1 lakh = ….10… ten thousand
(b) 1 million = …10… hundred thousand
hundred thousand = 100000
1 million = 1,000,000
= 10 ×1,00,000
So, 1 million = 10 hundred thousands
(c) 1 crore = ….10…. ten lakh
1 crore = 10000000
= ten lakhs = 10 × 10,000
= 10 ten lakh
So, 1 crore........10... ten lakh.
(d) 1 crore = …10…million.
1 million = 1,000,000
1 crore = 1,00,00,000
= 10 × 1,000,000
1 crore = …10…million.
(e) 1 million = …10…. lakh.
ten lakh = 10,00,000
1 million = 1,000,000
= 10 × 1,00,00
1 million = …10…. Lakh

Q. 2 Place commas correctly and write the numerals:
a. Seventy-three lakh seventy-five thousand three hundred seven.
b. Nine crore five lakh forty-one.
c. Seven crore fifty-two lakh twenty-one thousand three hundred two.
d. Fifty-eight million four hundred twenty-three thousand two hundred two.
e. Twenty-three lakh thirty thousand ten.
a. Seventy-three lakh seventy-five thousand three hundred seven;
Answer:-
Let’s break the sentence first,
Seventy-three lakh = 73,00,000
Seventy-five thousand = 75,000
Three hundred and seven = 307
By adding the above numbers, we get,
73, 00,000 + 75,000 + 307
= 73, 00,000 + 75,307
= 73,75,307
b. Nine crores five lakh forty-one
Nine crore = 9,00,00,000
Forty-one = 41
Now add the above numbers,
9,0000,000 + 5,00,000 + 41
= 9,0000,000 + 5,00,041
= 9,05,00,041
c. Seven crores fifty-two lakh twenty-one thousand three hundred two,
Seven crore = 7,00,00,000
Fifty-two lakh = 52,00,000
Twenty-one thousand = 21,000
Three hundred and two = 302
By adding all the above numbers, we get,
= 7,00,00,000 + 52,00,000 + 21,000 + 302
= 7,0000,000 + 52,00,000 + 21,302
= 7,0000,000 + 52,21,302
= 7,52,21,302
d. Fifty-eight million four hundred twenty-three thousand two hundred two.
Fifty-eight million = 58,000,000
Four hundred twenty-three thousand = 423,000
Two hundred and two = 202
By adding above numbers we get,
= 58,000,000 + 4,23,000 + 202
= 58,000,000 + 4,23,202
= 58,423,202
e. Twenty-three lakh thirty thousand ten,
Twenty-three lakh = 23,00,000
Thirty thousand = 30,000
Ten = 10
Add the above numbers,
= 23,00,000 + 30,000 + 10
= 23,00,000 + 30,010
= 23,30,010

Q.3 Insert commas suitably and write the names according to Indian System of Numeration:
(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.
Solution (a)- 8,75,95,762
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 + ninety-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
So = Eight crore seventy-five lakh ninety-five thousand seven hundred sixty-two
Solution (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
Solution (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 ninety-nine lakh forty-six
Solution (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.
