Answers :

1) Answer: B

Let the required women = x

2m =3w

3w *24 = (6m+ x)*6

= > 3w *24 = (9w + x) *6

= > 3*24=(9+x)*6

= >72=54+6x

= >18=6x

= > x= 3

2) Answer: D

(N – 9)/N = 3/4

3N = 4N – 36

N = 36

Divya = 1/6 * 36 = 6

Divya’s age after 4 years = 6 + 4 = 10 years

3) Answer: A

5x – 3x = 12

x = 6

CP of Pencil = 6 * 3 = Rs.18

SP of Pencil = 18 * 90/100 = Rs.16.2

4) Answer: B

Investment of Anu = x

Investment of Banu = x * 50/100 = x/2

Investment of Manu = x/2 * 100/300 = x/6

Profit ratio of Anu, Banu and Manu = x * 4y:x/2 * 5y:x/6 * 6y

= 4xy:5xy/2:xy

= 8:5:2

Profit of Manu = 2/15 * 3000 = Rs.400

5) Answer: B

Let the radius = 100 and height = 100

= > old area : new area = 2*π*100*100: 2*π*130*120

= > old area : new area = 25: 39

Required % = 14*100/25 = 56%

6) Answer: B

32² + 18² – (37 * 31) = ?

1024 + 324 – 1147 = ?

? = 201

7) Answer: A

2(1/4) + 6(1/2) – 3(1/8) + 1(3/8) = ?

9/4 + 13/2 – 25/8 + 11/8 = ?

(36 + 104 – 50 + 22)/16 = ?

? = 7

8) Answer: D

(5832)^(1/3) * (2744)^(1/3) = ?² – 4

18 * 14 = ?² – 4

? = 16

9) Answer: C

899 ÷ 31 + 19 * 9 = ? * 8

29 + 171 = ? * 8

? = 25
