Directions(1-5): Find the wrong number of the following series.
- 29, 37, 21, 43, 13, 53
2137534329Option D
29 + 1 × 8 = 37
37 – 2 × 8 = 37 – 16 = 21
21 + 3 × 8 = 21 + 24 = 45
45 – 4 × 8 = 45 – 32 = 13
13 + 5 × 8 = 13 + 40 = 53 - 10, 8, 13, 35, 135, 671
8671133510Option B
10 × 1 – 2 = 8
8 × 2 – 3 = 13
13 × 3 – 4 = 35
35 × 4 – 5 = 135
135 × 5 – 6 = 675 – 6 = 669 - 150, 290, 560, 1120, 2140
11202140290150560Option A
150 × 2 – 1 × 10 = 300 – 10 = 290
290 × 2 – 2 × 10 = 580 – 20 = 560
560 × 2 – 3 × 10 = 1120 – 30 = 1090
1090 × 2 – 4 × 10 = 2180 – 40 = 2140 - 1, 5, 13, 31, 61, 125
1356112531Option E
1 + 2^2 = 1 + 4 = 5
5 + 2^3 = 5 + 8 = 13
13 + 2^4 = 13 + 16 = 29
29 + 2^5 = 29 + 32 = 61
61 + 2^6 = 61 + 64 = 125 - 8, 11, 17, 47, 128, 371
81712847371Option B
8 + 3 = 11
11 + 3^2 = 11 + 9 = 20
20 + 3^3 = 20 + 27 = 47
47 + 3^4 = 47 + 81 = 128
128 + 3^5 = 128 + 243 = 371 - By what percent the boys in C3 post in factories T3 and T4 together are more or less than the girls on C2 post in factories T1 and T2 together ?
35%47%38%40%42%Option B
Boys in C3 post = 64/100*2250+30/100*1700 = 1950
Girls in C2 post = 64/100*1350+30/100*1550 = 13290
Required% = 621/1329*100 == 47% - Find the ratio of total girl in C3 in factories T3 and T4 together and girl C1 in factory T2.
2:33:54:12:75:9Option C
Required ratio = [36/100*2250 + 70/100*1700]/[40/100*1250] = 4:1 - The girls in Manager post in company T3 can finish a certain piece of work in 20 days. After they began to work, 20 girls left the work after every 5 days. Find the number of days required to complete the work.
21(13/19) days23(11/17) days21(12/15) days21(13/17) days19(10/17) daysOption D
No. of girls = 56/100*750 = 420
420*20 = 420*5 + 400*5 + 380*5 + 360*5 + 340*x
=> 340 + x = 600
=> x = 1(13/17)
Required days = 5+5+5+5+1(13/17)
= 21(13/17) days - Find the average number of boys in C1 post in all factories together .
300454400350520Option C
Required average = ½[30/100*950 + 60/100*1250+44/100*750+20/100*1050+50/100*850] = 1/5*2000
= 400 - The average age of boy in C3 in factory T4 is 74 years. Two-fifth of them have average age of 76 years, 50% of remaining have average age 4 years less that of all boy designers. Find the average age of remaining boy designers.
71 year 2 months84 year 3 months66 year 4 months77 year 5 months75 year 4 monthsOption E
Number of boy in C3 = 30/100*1700 = 510
510*74 = 204*76 + 153*70 + 153*x
=> x = 75 year 4 months
