Write the value of
30,00,000++20,000++10+5=39,20,715
9,00,000
700
LHS will be an expanded form of the RHS.
By comparing both sides we get,
RHS=39,20,715
LHS=30,00,000+9,00,000+20,000+700+10+5
Hence, on comparing LHS and RHS box can be replaced by 9,00,000 and 700 .
+7,000+100++9=57,189
80,000,000++500,000+6,000+500+30=84,506,530
50,00,00,000++6,00,000+90,000+6,000++70+7=50,16,96,777
80 lakh 2 ten thousand thousand 2 hundred 7 ones=80,25,207
