  5. Introduction Example 15. Out of the shirts produced in a factory, 15% are defective, while 20% of the rest are sold in the domestic market. If the remaining 8840 shirts are left for export, then the number of shirts produced in the factory is Solution: Let total shirts produced 100x Defective 15x Rest 85x Shirts sold in domestic market 17x Remaining shirts = 68x So,68x 8840 100x 13000.


  6. Introduction Example 16. In a village, the production of food grains increased by 40% and the per capita production of food grains increased by 27% during a certain period. The percentage by which the population of the village increased during the same period is nearest to Solution: Required percentage is (40/127-1) * 100 10%


  7. Introduction Example 17. The number of votes not cast for the PNC Party increased by 25% in the National General Election (NGE) as compared to the previous Assembly Polls, and as a result the PNC Party lost In the NGE try a majorlty of twice as many yotes by which it had won the Assembly Polls.

Solution: Total Votes 2,60,000 Let x voters voted against the party in the Assembly Poll. Then votes in favour 260000- Therefore, majority of votes by which party won in previous poll - 260000-x-x = 260000-2x Next year votes against the PNC party increased by 25% So, votes against the party in general election1.25 x And votes polled in favour of the party Total votes - votes against 260000 - 1.25x


  8. Introduction Therefore, majority of votes by which party lost in general election 1.25x- (260000 1.25x) 2.5x - 260000 It is given that, PNC Party lost by a majority twice as large as that by which it had won the Assembly Polls, Therefore 2.5x-260000 = 520000-4X 6.5x 780000 x 1,20,000 Therefore, votes polled by the voters for the party in Assembly Polls for previous year = (2,60,000-x) = (2,60,000-1,20,000) = 1,40,000.

  10. Introduction Example 18, Dipin's score is 15% more than that of Rafi and Rafi's score is 10% less than that of Chandar. If the difference between the scores of Dipin and Chandar is 14, then what is the score of Rafi? Solution: Dipin's score 115/100 x Rafi's score Rafi's score =90/100 x chandar's score Let Chandar's score be I15/100 x 90/100 x-x=14 207/200 X-X-14 7x = 14 x 200 => X = 400 Rafi's score 90/100 x 400 360


  11. Introduction Example 19.40% population of a village are women and the rest are men. 60% of the women and 45% of the men are above 30 years old. If the total population of the village is 20000, then what can be the maximum number of people in the village who are 30 years old?


  12. Introduction Example 19.40% population of a village are women and the rest are men, 60% of the women and 45% of the men are above 30 years old. If the total population of the village is 20000, then what can be the maximum number of people in the village who are 30 years old? Solution: Total population = 20000 So, men and women in the village = 12000, 8000 Women above 30 years = 4800 Men above 30 years 5400 Number of person below or equal to 30 years 20000 (4800 +5400) 9800
