Question

If M. D. is $12$, the value of S.D. will be

• A. 15
• B. 12
• C. 24
• D. None of these

Answer 1

Answer: (A)

15

Answer 2

We know that $D = \frac{5}{6} \times M.D.$
$= \frac{5}{6} \times 12 = 10$
$\therefore \, S.D = \frac{3}{2} \times D$
$= \frac{3}{2} \times 10$
$\Rightarrow \, S.D. = 15$
