Answer 1

The answer is below

Explanation:

a)

i) 1 lakhs = 100000, therefore:

1 million =
`(1000000)/(100000) *1\ lakh=10 \ lakh`

ii) 1 lakhs = 100000, therefore:

5 million =
`(5000000)/(100000) *1\ lakh=50 \ lakh`

b)

i) 1 crore = 10 million. therefore:

10 million =
`(10000000)/(10000000)*1\ crore=1\ crore`

ii) 1 crore = 10 million. therefore:

40 million =
`(40000000)/(10000000)*1\ crore=4\ crore`

c)

i) 1 arab = 1 billion, therefore:

1 biilion =
`(1000000000)/(1000000000)*1\ arab=1\ arab`

ii) 1 arab = 1 billion, therefore:

20 biilion =
`(20000000000)/(1000000000)*1\ arab=20\ arab`

d)

i) 1 lakhs = 100000, therefore:

20 lakhs =
`20*100000=2000000=2\ million`

ii) 1 crore = 10 million. therefore:

5 crore =
`5*10000000=50000000=50\ million`

e)

i) 1 arab = 1 billion, therefore:

30 arabs =
`30 *1000000000=30000000000=30\ billion`

ii) 1 kharab = 100 billion, therefore:

2 kharab = 2 * 100 billion = 200 billion
