Question : Mid-latitude deserts (BWk) are found between 35° and______ N and S, which are poleward of subtropical high-pressure areas.
Option 1: 70°
Option 2: 60°
Option 3: 79°
Option 4: 40°
Correct Answer: 60°
Solution : The correct option is 60°.

Question : Which of the following is not true about gymnosperms?
Option 1: The dominant phase is sporophytes
Option 2: Vascular bundles are absent
Option 3: Spores are heterosporous
Option 4: Flowers are absent
Correct Answer: Vascular bundles are absent
Solution : The correct option is Vascular bundles are absent.
Gymnosperms contain vascular bundles. Vascular bundles are collections of specialised tissues that transport water, nutrients, and sugars throughout the plant. These vascular bundles are found in gymnosperm stems, and can be arranged in a
Question : It is given that $\triangle \mathrm{PQR} \cong \triangle \mathrm{MNY}$ and $PQ=8\ \mathrm{cm}, \angle Q = 55°$ and $\angle P = 72°$. Which of the following is true?
Option 1: $\mathrm{NY}=8 \mathrm{~cm}, \angle \mathrm{Y}=72^{\circ}$
Option 2: $\mathrm{NM}=8 \mathrm{~cm}, \angle \mathrm{M}=53^{\circ}$
Option 3: $\mathrm{NM}=8 \mathrm{~cm}, \angle \mathrm{Y}=53^{\circ}$
Option 4: $\mathrm{NY}=8 \mathrm{~cm}, \angle \mathrm{N}=55^{\circ}$
Correct Answer: $\mathrm{NM}=8 \mathrm{~cm}, \angle \mathrm{Y}=53^{\circ}$
Solution : In $\triangle PQR,$ $\angle P + \angle Q +\angle R = 180°$ ⇒ $72°+55°+\angle R = 180°$ ⇒ $\angle R = 180° - 127°$ ⇒ $\angle R = 53°$ As $\triangle \mathrm{PQR} \cong \triangle \mathrm{MNY}$, ⇒ $\angle Y = \angle R=53° $

Question : $\triangle$ LON and $\triangle$ LMN are two right-angled triangles with common hypotenuse LN such that $\angle$ LON = $90^{\circ}$ and $\angle$ LMN = $90^{\circ}$. LN is the bisector of $\angle$ OLM. If LN = 29 cm and ON = 20 cm, then what is the perimeter (in cm) of $\triangle$ LMN?
Option 1: 67
Option 2: 62
Option 3: 65
Option 4: 70
Correct Answer: 70
Solution : Given: $\triangle$LON and $\triangle$LMN are two right-angled triangles with common hypotenuse LN such that $\angle$LON = $90^{\circ}$ and $\angle$LMN = $90^{\circ}$. LN is the bisector of $\angle$OLM also, LN = 29 cm and ON = 20 cm. In $\triangle$LON, LO = $\sqrt{29^2-20^2}=\sqrt{441}$ = 21 cm

Question : A man bought some eggs of which 10% are rotten. He gives 80% of the remaining to his neighbours. Now he is left out with 36 eggs. How many eggs did he buy?
Option 1: 40
Option 2: 100
Option 3: 200
Option 4: 72
Correct Answer: 200
Solution : Let the number of eggs he bought be 100 units. Eggs, after removing rotten one = 90 units Eggs given to neighbour = 80% of 90 = 72 units. Now, remaining eggs = 90 - 72 = 18 units. Now, on comparing, we get, 18
