Answers :
Directions (1-5) :
1) Answer: B
Total number of peoples went for a mall in Thursday = 600
The ratio of total number of peoples went for a mall in Tuesday, Wednesday and Thursday = 2: 3: 4
4’s = 600
1’s = 150
Total number of peoples went for a mall in Tuesday = 2*150 = 300
Total number of peoples went for a mall in Wednesday = 3*150 = 450
(60/100)*Total number of peoples went for a mall = 600 + 300 + 450
Total number of peoples went for a mall = 1350*(100/60) = 2250
2) Answer: D
Total number of peoples went for a mall = 2250
Total number of peoples went for a mall in Monday = 2250*(40/100) = 900
Total number of peoples went for a mall in Tuesday = 300
Required % = (900/300)*100 = 300 %
3) Answer: A
Total number of peoples went for a mall in Wednesday = 450
The ratio of total number of male, female and children went for a mall in Wednesday = 4: 5: 6
15’s = 450
1’s = 30
Total number of male went for a mall in Wednesday = 120
Total number of Children went for a mall in Wednesday = 180
Total number of peoples went for a mall in Monday = 2250*(40/100) = 900
The ratio of total number of male, female and children went for a mall in Monday = 9 : 10 : 11
30’s = 900
1’s = 30
Total number of male went for a mall in Monday = 270
Total number of children went for a mall in Monday = 330
Required difference = (180 + 330) – (120 + 270) = 510 – 390
= > 120
4) Answer: C
Total number of peoples went for a mall in Tuesday = 300
Total number of peoples went for a mall in Wednesday = 450
Required % = [(450 – 300)/450]*100 = 33.33 % = 35 %
5) Answer: B
Total number of peoples went for a mall in Wednesday = 450
The ratio of total number of male, female and children went for a mall in Wednesday = 4: 5: 6
15’s = 450
1’s = 30
Total number of female went for a mall in Wednesday = 150
Total number of peoples went for a mall in Monday = 2250*(40/100) = 900
The ratio of total number of male, female and children went for a mall in Monday = 9 : 10 : 11
30’s = 900
1’s = 30
Total number of female went for a mall in Monday = 300
Required ratio = 150: 300 = 1: 2
Directions (6-10) :
6) Answer: B
Total mobiles exported by company D and F= 35000*2= 70000
Mobile exported by company D in 2014= 30/100* 35000= 10500
Mobile exported by company D in 2015= 10500/2= 5250
So,
Mobile exported by company F= 70000- 5250= 64750
Percentage of production exported by company F in 2015
= > (64750/90000)*100 = 72%
7) Answer: B
Mobile exported by company E in 2015 = 40000*(70/100) = 28000
Mobile exported by company E in 2014 = 50000- 28000 = 22000
Mobile exported by company E in 2016 = (22000/11)*5 = 10000
Number of mobiles produced by company E = (10000/80)*100 = 12500
8) Answer: D
Total number of mobiles exported by company A in 2014 and 2015
= 40/100* 20000 + 60/100* 50000
= 8000 + 30000
= 38000
Mobile exported by company C in 2014 and 2015= 38000 *3/2= 57000
Mobile exported by company C in 2015
= 57000 – (26000* 20/100)
= 51800
So,
Percentage of export by company C
= (51800/80000)*100 = 64.75 %
9) Answer: D
Number of defective mobile exported by B in 2014
= 45000*42/100* 20/100=3780
Number of defective mobile exported by company B in 2015= 3780/7* 5= 2700
Number of mobiles exported by company B= 2700/13.5 * 100= 20000
So,
Percentage of mobile exported by company B in 2015
= > (20000*100)/30000 = 66.66 % = 67 %
10) Answer: C
Mobile exported by A, B and D in 2014
= 40*20000/100 + 42* 45000/100 + 30* 35000/100
= 8000 + 18900 + 10500
= 37400
Mobile exported by company A and E in 2015
= 50000*60/100 + 70*40000/100
= 30000 + 28000
= 58000
Required percentage = (37400*100)/58000 = 65%
