Exercise 7
(1) No. of persons visited the shrine during these two years =
(6378907 + 7865089) = 14243996
(2) Total no. of bags produced by the three factories =
(23807575 + 19728686 + 8962347) = 52498608
(3) Total population of the city =
(5726439 + 4439675 + 2016348) = 12182462
(4) The population of male = (2359324 + 6813675) = 9172999
Total population of the city = (9172999 + 6813675) = 15986674
(5) Total sales receipt of the company in the year 2012 =
(13047546 + 7973674) = 21021220
Now, Total sales receipt of the company during these two years =
(13047546 + 21021220) = 34068766
(6) Bicycles produced in 2nd year =
(6736265 + 1374589) = 8110854
Now, Bicycles produced during these two years =
(6736265 + 8110854) = 14847119
(7) Total no. of votes registered =
(678509 + 462397 + 97685 + 16489 + 45716) = 1300796
(8) The population of the state =
(1623540 + 9768678 + + 6437945 + 2682635 +698781)
= 21211579
(9) The number is =
(35637844 + 7674156)
= 43312000

Exercise 9
(1) The number is = (7016418 – 6437859) = 578559
(2) The number is 7102340 – 6824572 = 277768
(3) The number is 6164324 – 5678469 = 485855
(4) The number is = 9005413 – 7906547 = 1098866
(5) The other number is = 13604050 – 7824361 = 5779689
(6) Total failed candidates = 1008314 – 789425 = 218889
(7) The increase in the production of switches = 6010016 – 5365129 = 644887
(8) The other candidates receive = 6872403 – 983516 = 5888887
(9) Total no. of boys in the school are = 7651234 – 2963459 = 46877775
(10) Total no. of men and women = (6751574 + 6036425) = 12787999
Therefore, Total numbers of children are =
15207635 – 12787999 = 2419636
(11) Total number of candidates passed in first division and second division =
197528 + 238604 = 436132
Therefore, No. of candidates passed in third division =
506212 – 436132 = 70080
