Example : In an examination, 180765 students appeared. 89929 students
passed. How many students failed ?
17 9
Solution : Students appeared = 180765 0 7 10 17 5 15
Students passed = 89929 1 8 0 7 6 5
\ Number of students failed – 8 9 9 2 9
= 180765 – 89929 0 9 0 8 3 6
= 90836
Example : The population of a town is 290745. There are 80670 men and
60907 women. The remaining are children. How many children
are there in the town ? 1
8 0 6 7 0
Solution : Number of men = 80670
+ 6 0 9 0 7
Number of women = 60907
1 4 1 5 7 7
Therefore, the total number of men and
women = 80670 + 60907
8 10 6 13 15
= 141577 2 9 0 7 4 5
Total population = 290745 – 1 4 1 5 7 7
1 4 9 1 6 8
Number of children = 290745 – 141577
= 149168
