Directions (1-5) :

Total production of company A, B and C = 80000

Total production of company A = 80000*(36/100) = 28800

Total production of company B = 80000*(42/100) = 33600

Total production of company C = 80000*(22/100) = 17600

The sold cars of company A = 28800*(7/12) = 16800

The unsold cars of company A = 28800 – 16800 = 12000

The sold cars of company C = 17600*(13/20) = 11440

The unsold cars of company C = 17600 – 11440 = 6160

The unsold cars of company B = 16800 – 2100 = 14700

The sold cars of company B = 33600 – 14700 = 18900 The total sold cars of company B = 18900

The total production of company C = 17600

Required difference = 18900 – 17600 = 1300

The total number of cars sold by company A = 16800

The total number of cars sold by company B = 18900

Required ratio = 16800: 18900 = 8: 9

The average sold cars of company A and B together

= > (16800 + 18900)/2 = 17850

The average unsold cars of company A and B together

= > (12000 + 14700)/2 = 13350

Required difference = 17850 – 13350 = 4500

Total production of company B = 33600

Total unsold cars of company A and C together

= > 12000 + 6160 = 18160

Required % = (33600/18160) * 100 = 185 %

The total sold cars of company A, B and C together

= > 16800 + 18900 + 11440

= > 47140

4x × (225)1/2 = 248 ÷ 8 + 929

4x * 15 = (248/8) + 929

4x = (31 + 929)/15

4x = 64

4x = 43

x = 3

450 ÷ 15 + 208 ÷ 8 – 16 = x2 – 41

(450/15) + (208/8) – 16 + 41 = x2

30 + 26 – 16 + 41 = x2

x2 = 81

x = 9

256(1/8) * 642 = 16a

44/8 * 43 * 2  = 42a

1/2 + 6 = 2a

13/4 = a

√4489 + √169 +? = 19 * 24

67 + 13 +? = 456

? = 376

767 ÷ 13 + 357 ÷ √289 =? * √16

59 + 21 =? * 4

? = 20
