Answer» Correct Answer - Option 1 : One gram is one-hundredth of one kilogram. Checking all statements one by one : 1) 1 kilogram = 1000 grams One-hundredth of one kilogram = 1/100 × 1000 grams = 10 grams So, the given statement is not correct. 2) 1 cm = 10 mm ⇒ one-tenth of 1 cm = 1/10 × 10 mm = 1 mm So, the given statement is correct. 3) 1 lakh = 100000 ⇒ 100000= 100 × 1000 So, 1 lakh equals a hundred thousand. ∴ The given statement is correct. 4) 1 crore = 10000000 One hundredth of a crore = 1/100 × 10000000 = 100000 which is one lakh so, this statement is also true.

Answer» Correct Answer - Option 1 : One gram is one-hundredth of one kilogram.

Checking all statements one by one :

1) 1 kilogram = 1000 grams

One-hundredth of one kilogram = 1/100 × 1000 grams = 10 grams

2) 1 cm = 10 mm

⇒ one-tenth of 1 cm = 1/10 × 10 mm = 1 mm

So, the given statement is correct.

3) 1 lakh = 100000

⇒ 100000= 100 × 1000

So, 1 lakh equals a hundred thousand.

∴ The given statement is correct.

4) 1 crore = 10000000

One hundredth of a crore = 1/100 × 10000000 = 100000

which is one lakh so, this statement is also true.
