Answers :
1) Answer: D
Weight of third lightest person=x
51*5=52*2+48*2+x
255-200=x
x=55 kg
2) Answer: A
The average weight of A, B and C=44 kg
The average weight of A, B, C, D and E=44*100/110=40 kg
The weight of D and E=40*5-44*3=68 kg
3) Answer: D
A = 9x
B = 7x
C = 9x *2/3 = 6x
7x – 6x = 21
x= 21 cm
A = 9 * 21 = 189 cm
B = 7 * 21 = 147 cm
Required average=(189 + 147)/2 = 336/2 = 168 cm
4) Answer: C
D = 60 kg
B = 60-12 = 48 kg
A = 48 + 8 = 56 kg
C = 60 + 12 = 72 kg
Required average=(60 + 48 + 72)/3 = 180/3 = 60 kg
5) Answer: D
Let the weight of B=14x kg
The weight of A=14x*5/7=10x kg
The weight of C=14x*125/100=17.5x kg
14x+10x+17.5x=83*3
41.5x=249
x=6
The weight of A=10*6=60 kg
The weight of B=14*6=84 kg
Required average=(60+84)/2=72 kg
6) Answer: D
Let the number of clerks in the company be x,
800*30 + 240*x = 300(30 + x)
24000 + 240x = 9000 + 300x
15000 = 60x
x = 15000/60 = 250
Total number of clerks in the company = 250
Shortcuts:
= > 3: 25
3’s = 30
1’s = 10
Total number of clerks in the company = 25’s = 250
7) Answer: C
Total runs = 324
First 3 Matches = 51 * 3 = 153
Last 4 Matches = 57 * 4 = 228
Run scored in the third match = 153 + 228 – 324 = 57 runs
8) Answer: D
Total weight of 20 girls=600 kg
Average weight of 20 girls=600/20=30 kg
Average weight of boys=30+10=40 kg
Total weight of boys=30*40=1200
Required average=(1200+600)/(30+20)=1800/50=36 kg
9) Answer: A
Boys = 1/3 * 15 = 5
Girls = 2/3 * 15 = 10
Total age of the class = 15 * 24 = 360 years
Total age of the boys = 5 * 16 = 80 years
Total age of the girls = 10 * x = 10x
360 = 80 + 10x
280 = 10x
x = 28 years
10) Answer: C
Arul + Tinu + Kavi + Divya = 68 * 4 = 272
Arul weight = 48 kg
Tinu weight = 5/6 * 48 = 40 kg
Kavi + Divya = 272 – 48 – 40 = 184
Average of Kavi and Divya = 184/2 = 92 kg
