solutions

1. Ans. A.
59, 60 ,61 ,64 ,79 ,185 ,1129
The differences of the series is 1,3,15,106…..
This can be formed on the basis like 1×1,1×3,3×5,15×7..so on
Hence the wrong no. is 185.
2. Ans. B.
330, 80, 280, 120, 250, 130, 240
The difference of 330 and 80=250 The difference of 80 and 280=200
The difference of 280 and 120=160 The difference of 120 and 250=130
The difference of 250 and 130=120 And this difference will be 110,
so the wrong no. is 130
3. Ans. C.
291, 147, 75, 39, 22,12,7.5
The series is 291−147=144 147−75=72 75−39=36 39−22=17 but this difference will be 18
So the wrong no. is 22
4. Ans. C.
1, 3, 9, 31, 129, 652
The series is 1×1+2=3 3×2+3=9 9×3+4=31 31×4+5=129 129×5+6=651
Hence the no. 652 is wrong
5. Ans. A.
the series is 26+1^2−1=26    26+3^2−1=34    34+5^2−1=58         58+7^2−1=106 and so on…..
Hence wrong no. is 27

6. Ans. A.

14. Ans. C.
Required ratio =504:36
14:1
15. Ans. A.
Total no. of employees in company D= 900×24/100 × 1/12 * 1.25−900×24/100 * 1.5 =297
16. Ans. E.
Quantity I: Let speed of current=x Speed of boat=x+5x Downstream speed=63/7x =3 X=3 Upstream speed=6x – x=5x=15kmph
Quantity II- 15 km/hr
Hence QuantityI = Quantity II or No relation
17. Ans. A.
Let no. be x,x+2,x+4,x+6…..
Quantity I = x+2+x+14=2x+16
Quantity II=x+4+x+10=2x+14
Hence Quantity I > Quantity II
18. Ans.
A. Qunatity1= x= −3,2
Qunatity11= y= −4,−3
Qunatity1> Qunatity11
19. Ans.
A. Quantity I – Rs. 550
Quantity II – let Marked price of article=M M×7/8 =1500 M= 1200/7
Hence Quantity I > Quantity II
20. Ans. A.
Quantity I =10 days
Quantity II=12 days
Hence Qunatity1> Qunatity11

Ratio of profit of A, B and C in scheme S1 80000×2:30000×3:50000×5= 16:9:25
In scheme S1 Profit of A=×200000=64000 Profit of B=×200000=36000
Profit of C=×200000=100000 Ration of profit of A and C in scheme S2 3000010000×3= 12:3
Profit of A in scheme S2 =×90000=72000
Profit of B in scheme S2 =×90000=18000 64000*100/18000 = 335 5/9%
28. Ans. A.
[(80000*R*3)/100]-[3000*{(R+5)/100}]=30000
R=15%
