Correct option is  A) 9

(क) 

9 = 9, 18, 27, 36, 45, 54, 63, 72

15 = 15, 30, 45, 60, 75

अतः 9 और 15 का समापवर्त्य जो 80 से कम हो = 45

(ख)

6 = 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72, 78

10 = 10, 20, 30, 40, 50, 60, 70

अतः 6 और 10 का समापवर्त्य जो 80 से कम हो = 30, 60

(ग) 

8 = 8, 16, 24, 32, 40, 48, 56, 64, 72

9 = 9, 18, 27, 36, 45, 54, 63, 72

अतः 8 और 9 का समापवर्त्य जो 80 से कम हो = 72

(घ)

7 = 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77

\(\overline {X}\)  = \(\cfrac{\sum X_i}{N}\)

  = \(\cfrac{10.25\,+\,9\,+\,4.75\,+8 \,+\,2.65\,+\,12\,+2.35}{7}\)

= \(\cfrac{49}{7}\)

\(\overline {X}\) = 7

Correct option is  C) 60-70

Correct option is  C) 34 

i) \(\frac{7}{11}\) of 330 

= \(\frac{7}{11}\) × 330 

= \(\frac{7}{11}\) × 11 × 30 

= 7 × 30 = 210

ii) \(\frac{5}{9}\) of 108 

= \(\frac{5}{9}\) × 108 

= \(\frac{5}{9}\) × 9 × 12 

= 5 × 12 = 60

iii) \(\frac{2}{7}\) of 16 

= \(\frac{2}{7}\) × 16

= \(\frac{2\times16}{7}\) 

= \(\frac{32}{7}\) or \(4\frac{4}{7}\)

iv) \(\frac{1}{7}\) of \(\frac{3}{10}\)

= \(\frac{1}{7}\) × \(\frac{3}{10}\)

= \(\frac{1\times3}{7\times10}\)

= \(\frac{3}{70}\)
