Let's solve the problems step by step.
Problem III:
We need to find how much 45,26,724 is less than 1,00,00,000.
To find this, we need to subtract 45,26,724 from 1,00,00,000.
1 , 00 , 00 , 000 − 45 , 26 , 724 = 54 , 73 , 276
So, 45,26,724 is 54,73,276 less than 1,00,00,000.
Problem IV:
We need to find the number of boys among the total students in classes X and XII in all the schools of the state.
The total number of students is 43,52,324, and out of these, 18,40,126 are girls.
To find the number of boys, we subtract the number of girls from the total number of students.
43 , 52 , 324 − 18 , 40 , 126 = 25 , 12 , 198
Therefore, the number of boys in classes X and XII is 25,12,198.
