The pattern is, – (2.5*1), + (2.5*2), – (2.5*3), + (2.5*4)

The answer is, 70

2. Answer c

The pattern is, ÷ 6, ÷ 5, ÷ 4, ÷ 3,..

The answer is, 7

3. Answer e

The difference of difference is, 3, 5, 7, 9,..

The answer is, 797

5. Answer b

The pattern is, *0.5,*1, *2, *4, *8,..

The answer is, 56

6. Answer a

5 vowels and 6 consonants are there in the above word, Vowels always come together, So we take that as, 7!

Total ways is,

= > (7!/2!*2!) * (5!/2!)

= > 75600

7. Answer c

Explanation:

The ratio of Profit= 1*(6) + 2*(6) : 2*(6) + 1*(6) : 3* (6) + (3/2)*(6)

= > 18 : 18 : 27

= > 2 : 2 : 3

8. Answer d

Explanation:

Total work= 15*8 = 120 work

3 days work= 15*3 =45 work

Remaining work= 120 -45 = 75 work

Required days = 75/12 = 6 ¼ days

9. Answer b

Explanation:

(P*4*6)/100 =240

P = 1000

Corresponding C.I,

C.I = P(1+(r/100)⁴) – P

= > 1000(1+(6/100)⁴) -1000

= > 1262.47696 -1000

= >262.47696

10. Answer e

Let total marks be x,

(20/100)*x + 60 = (32/100)x -84

(12/100)x = 144

X= 1200

Passing mark= (20/100)*1200 +60 =300

Passing % = (300/1200)*100 = 25%

Directions (Q. 11-15):

11. Answer a

(162*238)/100 + 5x = 2615 +89

5x= 2615+89 -385.56

5x= 2318.44 /5

X= 463.688

12. Answer c

(5/7)*(3/8)*(13/3) +225 = x-484

65/56 +709 = x

X= 1.16 +709 =710.16

13. Answer d

64³ ÷ 16⁷ × 256⁹ = 4^{x + 3}

4⁹ ÷ 4¹⁴ × 4³⁶ = 4^{x + 3}

4^{9 -14 +36} = 4^{x + 3}

31 = x+3

X=28

14. Answer b

= > (3/8) * (16/9) * (6/15) * (45/100) * 4850

= > (2 * 45 * 97) / 15

= > 582

15. Answer a

(24 × 24 × 6)/12 +512 +91 +837 = x³

288 +512 +91 +837 = x³

x³ = 1728

x = 12

Directions (Q. 16-20):
