Option 2 : (ii) and (iv)

Concept:

Number values: 

1 kilometer (km)  = 1000 metres (m)  

1 lakh = 100,000 = 1 hundred x 1 thousand

1 liter = 1000 milliliter (ml)

1 crore = 1 lakh x 1 hundred = 100 lakhs

Calculation:

To solve this question we have to go by option:

Option i. One meter is one-hundredth of one kilometer.

One-hundredth of one kilometer = 1 kilometer = 1/100 x 1000 = 10 metre ( not correct )

Option ii. One lakh is equal to one hundred thousand.

1 lakh = 1 hundred x 1 thousand ( correct )

Option iii. One milliliter is one-hundredth of one liter.

One-hundredth of one liter = 1/100 x 1000 ml = 10 ml ( not correct ).

Option iv. One crore is equal to one hundred lakh. 

1 crore = 1 hundred x 1 lakh = 1 hundred lakh. ( correct )
