**Solutions:**

**1.**D)

**2.**B) Pulses = 81 – 75 = 6

Oils = 90 – 82 = 8

Vegetables = 98 – 84 = 14

Fruits = 78 – 60 = 18

Milk = 77 – 62 = 15

Wheat = 97 – 78 = 19 greatest change

**3.**E) Average = (84 + 78 + 100 + 100 + 98) /5 = 460/5 = 92

**4.**A) Regular decrease in Fruits.

**5.**A) Highest variation

Pulses 81 – 63 = 13

Oils 90 – 64 = 26 highest variation

Vegetables 100 – 78 = 22

Fruits 78 – 60 = 18

Milk 77 – 62 = 15

Wheat = 97 – 74 = 23

**6.**B) Difference = 2150 – 1300 = 850

**7.**C) Required % = (500 x 100)/2150 = 23.25% ≈ 25%

**8.**D) Required % = (200 x 100)/1300 = 15.38% ≈ 15%

**9.**C) Average number of boys = 1300/5 = 260

**10.**E) Ratio = 350:250 = 7:5
