Q4. Ashwani has a certain amount of money with him. He can buy either 60 apples or 40 mangoes. He wants to spend only 70% of his money. So he buys 14 mangoes and some apples. Find out the number of apples purchased by Ashwani.
(a) 23
(b) 21
(c) 28
(d) 25
(e) 18

S4. Ans.(b)
Sol.
Amount required to buy either 60 apples or 40 mangoes = 100% available amount
Since 14 is 35% of 40
∴ Amount spent on buying 14 mangoes = 35% of available amount
Remaining money = (70% – 35%) of available money = 35% of available amount
Number of apples that can be purchased with 35% of available amount = 35% of 60 = 21

Q5. A contractor undertook to construct a building in 120 days with 25 workers. However, after 57 days he observed that only 16% of the work is complete. How many more workers need to be employed to complete the work in time?
(a) 12
(b) 21
(c) 15
(d) 24
(e) 30

S5. Ans.(c)
Sol.
Let the number of additional workers = M
Thus (25 + M) men will work for remaining 63 days to complete remaining 84% of the work lef.
∴ 84% of 120 × 25 = (25 + M) × 63
⇒ 40 = 25 + M
⇒ M = 15

Directions (6-10): In the following number series only one number is wrong. Find out the wrong number.

Q6. 9050,       5675,       3478,       2147,       1418,       1077,       950
(a) 3478
(b) 1418
(c) 5675
(d) 2147
(e) 1077

S6. Ans.(e)
Sol.
The pattern of number series is as follows:
9050 - 〖15〗^3 = 9050 – 3375 = 5675
5675 - 〖13〗^3= 5675 – 2197 = 3478
3478 - 〖11〗^3= 3478 – 1331 = 2147
2147 - 9^3= 2147 – 729 = 1418
1418 - 7^3= 1418 – 343 = 1075 ≠ 1077

Q7. 71, 90, 128, 185, 261, 365
(a) 365
(b) 128
(c) 185
(d) 90
(e) 261

S7. Ans.(a)
Sol.
The series is 71 +19 = 90
90 + 38 = 128, 128 + 57 = 185
185 + 76 = 261, 261 + 95 = 356
Hence there should be 356 in place of 365

Q8. 484     240     120     57     26.5     11.25     3.625
(a) 240
(b) 120
(c) 57
(d) 26.5
(e) 11.25

S8. Ans.(b)
Sol.
The series is :
÷2-2,÷2-2.......
So, 240 ÷ 2 -  2 = 118 ≠ 120

Q9. 3     5     13     43     176     891     5353
(a) 5
(b) 13
(c) 43
(d) 176
(e) 891

S9. Ans.(d)
Sol.
Series is : ×1+2,×2+3,×3+4…………….
So, 43 × 4 + 5 = 177
∴ 176 should be replaced by 177.

Q10. 12 25 52 55 57 115 117
(a) 55
(b) 117
(c) 25
(d) 52
(e) None of these

S10. Ans.(d)
Sol.
The series is ×2 + 1, × 1 + 2 alternately
