1) 1
2) 3
3) 2
4) 1.5
5) None of these

Solutions -  Preeti’s present age = x years
Nisha’s present age = 3x years
After seven years,
3x + 7 = 2 (x + 7)
3x + 7 = 2x + 14
x = 7
Preeti’s present age = 7 years
Nisha’s present age = 21 years
After another 14 years i.e. after 21 years
Preeti’s age = 28 years
Nisha’s age = 42 years
Required answer = 42/28 = 1.5

4. Nirmalya got 102 marks in Hindi, 118 marks in Science, 104 marks in Sanskrit, 114 marks in Maths and 96 marks in English. The maximum marks of each subject are 120. How much overall percentage of marks did Nirmalya get?
1) 89
2) 82
3) 77
4) 71
5) None of these

Solutions - Total marks obtained by Nirmalya = 102 + 118 + 104 + 114 + 96 = 534
Total maximum marks = 120 × 5 = 600
Required percentage 534/600 x 100 = 89

5. 6 women alone can complete a piece of work in 10 days, whereas 10 children alone take 15 days to complete the same piece of work. How many days will 6 women and 10 children together take to complete the piece of work ?
1) 7
2) 8
3) 6
4) 4
5) None of these

Solutions - In 1 day (6 × 10) women can complete the piece of work and in 1 day (10 × 15) childrenmncan complete the same piece of work.
So, 6 × 10 women ≡ 10 × 15 children
= 2 women ≡ 5 children
So, 6 women + 10 children = (15 + 10) children = 25 children
So, M1D1 = M2D2
So, 10 × 15 = 25 × D2
D2 = 10x15/25 = 6 days

Directions (Q. 6-10) : What should come in place of the question mark (?) in the followingnumber series?

1) 8940 2) 8680 3) 10080 4) 5030 5) None of these

Solutions - The pattern of the number series is as given below:
2 × 7 = 14
14 × 6 = 84
84 × 5 = 420
420 × 4 = 1680
1680 × 3 = 5040
5040 × 2 = 10080

7. 3 58 13 21 34 ?
1) 62 2) 57 3) 55 4) 74 5) None of these

Solutions -  The pattern of the number series is as given below:
3 + 5 = 8
8 + 5 = 13
13 + 8 = 21
21 + 13 = 34
34 + 21 = 55

8. 1 2 6 21 ? 445 2676
1) 88 2) 77 3) 52 4) 64 5) None of these

Solutions - The pattern of the number series is as given below:
1 × 1 + 1 = 2
2 × 2 + 2 = 6
6 × 3 + 3 = 21
21 × 4 + 4 = 88

1) 612 2) 347 3) 216 4) 343 5) None of these

Solutions -  The pattern of the number series is as given below:
33 = 27 ; 53 = 125
73 = 343 ; 93 = 729
113 = 1331, 133 = 21973
153 = 3375

1) 175.5 2) 162.5 3) 154.75 4) 156.25 5) None of these

Solutions - The pattern of the number series is as given below:
10400 ÷ 4 = 2600
2600 ÷ 4 = 650
650 ÷ 4 = 162.5
162.5 ÷ 4 = 40.625
