Marks 25      Time: 45 Minutes

Q 1 (A) Fill in the blanks ( 3 questions - 3 marks)

1) 1 crore = _________ million

Answer: 1 crore = 10,00,00,00

              1 million = 100,00,00

Now cross multiply we get

1 crore x 100,00,00 = 1 milliion x 10,00,00,00

Therefore 1 crore = (1 million x 10,00,00,00 )/ (100,00,00)

                            = 1 million x 10

Now 1 crore you can just write as crore and 1 million you can write as just million

Therefore crore = 10 million

Thus the answer is 10 million

2) ______ thousands make 1 crore

Answer: In similar fashion as above we write:

1 crore = 10,00,00,00

1 thousand = 1000

Now cross multiply we get

1 crore x 1000 = 1 thousand x 10,00,00,00

Thus 1 crore = 10,000 x 1 thousand

Therefore 10,000 thousands make 1 crore

3) 1 litre = _________ millilitre

Answer: This is straight forward and suppose to be byhearted there is no arithematic method to find the answer.
