Directions : Study the following pie charts carefully and answer the questions given beside.
Number of soldiers in army of a country is 10,00,000. Total females in the army are 2,80,000. There are 6 divisions within the army namely A, B, C, D, E and F. In the meeting of Defence Minister with Chief of Army staff, number of soldier and their status within each division in terms of male and female population were discussed. Chief of Army Staff gave the following pie charts to Defence Minister.
Population of each division in terms of percentage has been given in pie chart-1, and pie chart-2 gives the number of males in those divisions in terms of degrees within pie chart of total male population in the army.
Half of females from division A, one-fourth from division C and one-fifth from D were sent for special training. If the number of females on this training are represented on a pie chart then what corresponding angle the females of division C will make? (approximately)
None of these
Incorrect AnswerExplanation:
Females in division A = 1,00,000
Half of it = 1/2 × 1,00,000 = 50,000
Females in division C = 40,000
one-fourth of it = 1/4 × 40,000 = 10,000
Females in division D = 1,10,000
one-fourth of it = 1/5 × 1,10,000 = 22,000
Total females on training = 82,000
On a pie chart we should have,
82,000 = 360°
In division C has 10,000 on training,
10,000 on pie chart =( 10,000 × 360°)/82,000
= 43.9 = 44° (approximately)
Hence, option C is correct.
