Solution
In 2005,
A = 0.20 × 42980 = 8596
B = 0.06 × 42980 = 2579
C = 0.10 × 42980 = 4298
D = 0.15 × 42980 = 6447
E = 0.27 × 42980 = 11605
F = 0.22 × 42980 = 9455
C + D = 4298 + 6447 = 10745
2.In 2006,
A = 10700
B = 0.10 × 48640 = 4864
C = 0.11 × 48640 = 5350
D = 0.09 × 48640 = 4377
E = 0.27 × 48640 = 13133
F = 0.21 × 48640 = 10214
% change during 2005-2006,
A = [(10700 - 8596)/8596] × 100 = 24.5% (approx)
B = [(4864 - 2579)/2579] × 100 = 88.6% (approx)
C = [(5350 - 4298)/4298] × 100 = 24.5% (approx)
D = [(6447 - 4377)/6447] × 100 = 32.1% (approx)
E = [(13133 - 11605)/11605] × 100 = 13.2% (approx)
F = [(10214 - 9455)/9455] × 100 = 8% (approx)
The % change was maximum for B.
3.(4864 - 2579) = 2285
4.(5000/48640) × 100 = 10% (approx)
5.(10700/8596) × 100 = 125% (approx)
6.For Course D,
No. of girls = 30% of 800 = 240
No. of students = (35 × 1/100 × 1200) = 420
Therefore, no. of boys = (420 - 240) = 180
Required ratio = 180 : 240 = 3 : 4
7.Number of boys,
in Course E = (12% of 1200 - 14% of 800) = (144 - 112) = 32
in Course F = (13% of 1200 - 14% of 800) = (156 - 112) = 44
in Course A = (20% of 1200 - 30% of 800) = (240 - 240) = 0
in Course D = (35% of 1200 - 30% of 800) = (420 - 240) = 180
in Course C = (5% of 1200 - 2% of 800) = (60 - 16) = 44
Obviously pair C and F is the answer.
8.For Course E,
No. of girls = (14% of 800) = 112
No. of boys = 32 Required% = (80/32) × 100 = 250
9.In Course A, the number of boys the minimum.
10.No. of girls in Course C = 2% of 800 = 16
