Answers :

1). Answer: b)

√-36= 6√-1

√- 16= 4√-1

√-36 ×√-16 = 6√-1×4√-1

= 24 × (-1)

= – 24

2). Answer: a)

Since the number of women leaves every day is equal to the number of women working for 12 days are in Arithmetic Progression (A.P)

Let n be the number of women employed for the work.

Common difference, d = − 10

No of workers = n

D1= 8

D2 = 12

m1× d1= m2 ×d2

8 x n = 12/2(2(n) + (12 − 1) (−10))

4n = 3(2n – 110)

4n = 6n – 330

2n = 330

N = 165

3). Answer: b)

4). Answer: c)

Let the age of Sharma be x years.

The ages of his two sons are y and z respectively.

yz = 24 —– (i)

y – z =  2 ——- (ii)

Solving (i) and (ii), y = 6 , z = 4

y + z = 10

x= 3(y + z) —— (iii)

x = 3×10 =30

Age of Sharma five years hence = 30+ 5=35

5). Answer: c)

Let the CP be x

SP1 = 0.95 x

SP2 = 0.95 x + 30 , Profit = 10%

Profit = SP – CP

10x/100 = 0.95 x+ 30 – x

0.1 x = – 0.5 x+ 30

0.6x = 30

x = 50

To have 30 % profit, Selling Price = 130/ 100 x 50 = 65

Direction (6-9) :

6). Answer: a)

Average Production = (110+ 90+ 45+ 130+180)/5 = 555/5 = 111

Average Demand = (120+ 80+ 50+110+170)/5 = 530/5 = 106

Difference= 111 – 106 = 5

7). Answer: c)

Answer: Production of company A= 110

Demand of Company C = 50

Required Percentage = 110/50 x100= 220%

8). Answer: c)

Number of companies having more demand than production = 2
