Question : The radii of two concentric circles are 13 cm and 8 cm. AB is the diameter of the bigger circle and BD is a tangent to the smaller circle touching it at D and the bigger circle at E. Point A is joined to D. The length of AD is:
Option 1: 20 cm
Option 2: 19 cm
Option 3: 18 cm
Option 4: 17 cm
Correct Answer: 19 cm
Solution : Let the line BD intersect the bigger circle at point C. Join AC. OD $\perp$ BD ⇒ OD $\perp$ BC So, BD = DC ⇒ D is the midpoint of BC. Also, O is the midpoint of AB. In $\triangle$BAC, O is the midpoint

Question : ABCD is a rhombus with $\angle$ABC = 52°. The measure of $\angle$ACD is:
Option 1: 54°
Option 2: 26°
Option 3: 48°
Option 4: 64°
Correct Answer: 64°
Solution : Since opposite angles of a rhombus are equal So, $\angle$ADC = $\angle$ABC = 52° Also, $\angle$DAC = $\angle$DCA = $x$ (say) [since AD = DC] In $\triangle$ ADC, $\angle$ADC + $\angle$DAC + $\angle$DCA = 180° ⇒ $x+x+52°$ = 180° ⇒ $x$ = 64° ⇒ $\angle$DCA

Question : The minimum value of $2\sin^{2}\theta+3\cos^{2}\theta$ is:
Option 1: 0
Option 2: 3
Option 3: 2
Option 4: 1
Correct Answer: 2
Solution : Given: $2\sin^{2}\theta+3\cos^{2}\theta$ = $2\sin^{2}\theta+3(1-\sin^{2}\theta)$ = $2\sin^{2}\theta+3-3\sin^{2}\theta)$ = $3-\sin^{2}\theta$ For minimum value of $(3-\sin^{2}\theta)$ by putting $\sin^{2}\theta=1$ ⇒ $3-1=2$ Hence, the correct answer is 2.
Question : In human beings, the small intestine is coiled and is about ______ metres long.
Option 1: 1 to 1.5
Option 2: 3 to 3.5
Option 3: 2 to 2.5

Question : Simply the given expression: (5p + 3q)(5p – 3q)
Option 1: 25p2 – 9q2 + 30pq
Option 2: 25p2 – 9q2
Option 3: 25p2 + 9q2
Option 4: 25p2 + 9q2 – 30pq
Correct Answer: 25p2 – 9q2
Solution : Given: (5p + 3q)(5p – 3q) = (5p)2 – (3q)2 = 25p2 – 9q2 Hence, the correct answer is 25p2 – 9q2.
