1Million=10 Lac ₹ Confusion !

◆● I want to know about it please any body can let please◆●
Before some days ago Forbs magazine declared the list of the Richest persons of the world . And for it they kept graph of 300 crore in indian currency or 300 million $
In indian measure—
1 m 10 lac
10 m 100 lac. 1crore
100 m 1 arab
*Yes on this scale of currency
India’s most buzzing cricket star of his time and the 1st professional cricketer
Sunil Gavaskar
Whose asset or nett Worth is 30 million $
It means in indian currency his property is only 3 crore…..!!!!!??????
Okay but when I saw Amitabh Bachchon’s capital whom he would part equally to his two children …..
Then I got confused what is it and what is that and what is the real mirror
Yes
Amitabh’s property right now as per the pic is
33.5 $
And in indian currency or rupee it rests–2453896500
It means
2 arab
45 crore
38 lac
96 thousand
500 hundred

I ask ……..How….???????
*If we count
I million as. 10 lacs
Then in 10 million 100 lac
It means in indian rupees
It would be only
3 crore 45 lac 38 thousand
965 hundred rupees
*So dear friends
Why is this variation come through have both counts
*I was in doubt to have seen the nett worth of Sunil Gavaskar and as per count in indian rupees rest 3 crore only
And couldn’t believe
Because in other search
Gavaskar’s yearly income is being shown 76 lac per year through commentary
Article writing
His books’ royalty
His hotel at Dubai
Pension from BCCI
So how can it possible that his asset tally rests only 3 crore indian currency or 30 millions $

I am curious to know about this
Please fellows
If among (EEE) us anyone can clarify it.
There are fellows in this group who are good mathematicians and by science-mathemarics stream well known with this term.
