(B) Company N

(C) Company O

(D) Company P

(E) Company Q

 

Answer 1. (B) 1.4

Explanation:

Average number of type A Kajal = (20 + 25 + 22 + 30 + 28)/ 5

= 125/5 = 25

Average number of type C Kajal = (24 + 35 + 30 + 17.5 + 25.5)/ 5

= 132/5 = 26.4

Difference = 26.4 – 25 = 1.4

 

Answer 2. (A) 83%

Explanation:

Kajal of type B produced by company O and P = 27.5 + 22.5 = 50

Kajal of type C produced by company N and Q = 35 + 25.5 = 60.5

Required percentage = 50/60.5 × 100 = 82.64 ≈ 83%

 

Answer 3. (E) None of theseExplanation:

All types of Kajal produced by company M = 20 + 28 + 24 = 72

All types of Kajal produced by company Q = 28 + 22 + 25.5 = 75.5

Required ratio = 72 : 75.5

= 144 : 151

 

Answer 4. (C) 20

Explanation:

All types of Kajal produced by company M = 20 + 28 + 24 = 72

All types of Kajal produced by company R = 72 × 125% = 90

Type A : Type B : Type C = 3 : 4 : 2

Kajal of type A produced by company R = 90/9 × 3 = 30

Kajal of type B produced by company R = 90/9 × 2 = 20

Kajal of type C produced by company R = 90/9 × 4 = 40

Required Difference = 40 – 20 = 20

 

Answer 5. (A) Company M

Explanation:

All types of Kajal produced by company M = 20 + 28 + 24 = 72

All types of Kajal produced by company N = 25 + 32 + 35 = 92

All types of Kajal produced by company O = 22 + 27.5 + 30 = 79.5

All types of Kajal produced by company P = 30 + 22.5 + 17.5 = 70

All types of Kajal produced by company Q = 28 + 22 + 25.5 = 75.5

Company M has the least production.
