**Answers:-**

**1.(4)**

Total number of luxury watches sold by stores C and H together = Total number of (luxury + sports) watches sold by stores C and H together – Total number of sports watches sold by stores C and H together= (14 + 9)% of 56000 – (7 +.12)% of 32000 = 12880 – 6080 = 6800

Total number of sport and luxury watches sold by stores F and H together = (8 + 9)% of 56000

= 17% of 56000 = 9520

Therefore, required percentage =(9520- 6800)/9520x 100%=28 4/7%

**2.(2)**

Number of watches (sports and luxury watches) sold by store ID = 15% of 56000 = 8400

Number of sports watches sold by stores C, F and G together = (7 + 8 + 6)% of 32000 = 21% of 32000 = 6720

Therefore, required percentage

(8400 – 6720)/6720 x 100% = 1680/6720 x 100% = 25%

**3.(1)**

Total number of sports watches sold by stores A and B together

= (16 + 16) % of 32000 = 32% of 32000 = 10240

Total number of watches (sports and luxury) sold by stores C and F together = (14 + 8) % of 56000 = 22% of 56000 = 12320

Therefore, required ratio = 10240 : 12320 = 64 : 77

**4.(2)**

**5.(4)**

**6.(1)**

**7.(5)**

**8.(1)**

**9.(4)**

in 1999, average employment per factory is greater than 1998 and less than 2000.

**10.(2)**

in 1996, for 20100 factories , employees = 13,245,900; average = 609, total employees = 18,361,350. So average for remaining factories = 509.

**11.(1)**

total employment in 1999= 36240 x 736.

Total employment in 1996 = 609 x 30150,

Ratio = (36240×736)/(30150×609)=1.45

**12.(4)**

From the figure it can be seen that the maximum increase in the number of factories is in 1995- 2000.

**13.(4)**

we do not have year wise data in between 1975- 1980 & similarly between 1980-1985,etc.
