Answer : Option A

Explanation :

Number of Managers working in the Company:

In 1995	= 760.
In 2000	= (760 + 280 + 179 + 148 + 160 + 193) - (120 + 92 + 88 + 72 + 96)
	= 1252.

Percentage increase in the number of Managers

= [ \(\frac { (1252-760) } { 760}\) x 100] % = 64.74%

Number of Technicians working in the Company:

In 1995	= 1200.
In 2000	= (1200 + 272 + 240 + 236 + 256 + 288) - (120 + 128 + 96 + 100 + 112)
	= 1936.

Percentage increase in the number of Technicians

= [ \(\frac { (1936 - 1200)} { 12 00}\) x 100 ] = 61.33%

Number of Operators working in the Company:

In 1995	= 880.
In 2000	= (880 + 256 + 240 + 208 + 192 + 248) - (104 + 120 + 100 + 112 + 144)
	= 1444.

Percentage increase in the number of Operators

=[ \( \frac { (1444 -880)} {880 } \) x 100] %= 64.09%

Number of Accountants working in the Company:

In 1995	= 1160.
In 2000	= (1160 + 200 + 224 + 248 + 272 + 260) - (100 + 104 + 96 + 88 + 92)
	= 1884.

Percentage increase in the number of Accountants

= [ \(\frac { (1884-1160) } { 1160 }\) x 100] % =62.41%

Number of Peons working in the Company:

In 1995	= 820.
In 2000	= (820 + 184 + 152 + 196 + 224 + 200) - (96 + 88 + 80 + 120 + 104)
	= 1288.

Percentage increase in the number of Peons

= [ \( \frac { (1288-820) } { 820 } \)x 100]%= 57.07%

Clearly, the percentage increase is maximum in case of Managers
