A) 57.5 degrees	B) 67.5 degrees
C) 77.5 degrees	D) 87.5 degrees

Answer & Explanation Answer: B) 67.5 degrees

Angle traced by hour hand in $\frac{21}{4}$ 21 hrs = ${(\frac{360}{12} \times \frac{21}{4})}^{0}$ = $157 \frac{1^{0}}{2}$

Angle traced by min. hand in 15 min = ${(\frac{360}{12} \times 15)}^{0}$ = $90^{0}$

$\therefore$ Required Angle = ${(157 \frac{1}{2})}^{0} - 90^{0}$ = $67 \frac{1^{0}}{2}$

Q:

The diagonal of a rectangle is $\sqrt{41}$ cm and its area is 20 sq. cm. The perimeter of the rectangle must be:

A) 18	B) 28
C) 38	D) 48

Answer & Explanation Answer: A) 18

Explanation:

$\sqrt{(l^{2} + b^{2})} = \sqrt{41}$ (or) $l^{2} + b^{2} = 41$

Also, $l b = 20$

${(l + b)}^{2} = l^{2 +} b^{2} + 2 l b$ = 41 + 40 = 81

(l + b) = 9.

Perimeter = 2(l + b) = 18 cm.
