Question : Direction: If 23 x 16 = 184, 37 x 10 = 185, then 85 x 12 = ?
Option 1: 511
Option 2: 610
Option 3: 510
Option 4: 410
Correct Answer: 510
Solution : Here, in the given equations the first number is multiplied by the half of the second number to get the answer.
⇒ 23 x 16 = 184 ⇒ 23 x 8 / 2 = 184
⇒ 37 x 10 = 185 ⇒ 37 x 10
Question : Direction: If the word LEADER is coded as 20 – 13 – 9 – 12 – 13 – 26, how would you write LIGHT?
Option 1: 20 – 16 – 15 – 17 – 22
Option 2: 20 – 16 – 17 – 15 – 27
Option 3: 20 – 15 – 16 – 18 – 23
Option 4: 20 – 17 – 15 – 16 – 28
Correct Answer: 20 – 17 – 15 – 16 – 28
Solution : Given:
LEADER = 20 – 13 – 9 – 12 – 13 – 26
For LEADER; L → 12 + 8 = 20 ( place value and add 8 ); E → 6 + 8 = 13
Question : The areas of two similar triangles $\Delta ABC$ and $\Delta PQR$ are 36 sq. cm and 9 sq. cm, respectively. If $PQ$ = 4 cm, then what is the length of $AB$ (in cm)?
Option 1: 16 cm
Option 2: 12 cm
Option 3: 8 cm
Option 4: 6 cm
Correct Answer: 8 cm
Solution : Given: Two triangles $ABC$ and $PQR$ such that: $△ABC∼△PQR$. If two triangles are similar, then the ratio of the area of both triangles is proportional to the square of the ratio of their corresponding sides. So, $\frac{\text{area of }(\Delta ABC)}{\text{area of }(\Delta PQR)}=(\frac{AB}{PQ})^2$ ⇒
Question : The area of the circle with radius $y$ is $w$. The difference between the areas of the bigger circle (with radius $y$) and that of the smaller circle (with radius $x$) is $w^1$. So, $\frac{x}{y}$ is equal to:
Option 1: $\sqrt{1-\frac{w^1}{w}}$
Option 2: $\sqrt{1+\frac{w^1}{w}}$
Option 3: $\sqrt{1+\frac{w}{w^1}}$
Option 4: $\sqrt{1-\frac{w}{w^1}}$
Correct Answer: $\sqrt{1-\frac{w^1}{w}}$
Solution : Given: The area of the circle with radius $y$ is $w$. The difference between the areas of the bigger circle (with radius $y$) and that of the smaller circle (with radius $x$) is $w^1$. We know that the area of the circle is $\pi r^2$.
Question : In the given sentence, one word may have been incorrectly spelt. Select the correctly spelt word from the given alternatives. If there is no error, select 'No Error' as your answer.

So, the correct sentence is: The erroneous information spread rapidly across the nation and created a
Question : In the given figure, $\mathrm{MNOP}$ is a square of side $6\;\mathrm{cm}$. What is the value (in $\mathrm{cm}$) of the radius of a circle?
Option 1: $4.25$
Option 2: $3.75$
Option 3: $3.5$
Option 4: $4.55$
Correct Answer: $3.75$
Solution :
Given that $\mathrm{MNOP}$ is a square of side $6\;\mathrm{cm}$. Construction: Join $\mathrm{QC}$ and $\mathrm{PC}$. $\mathrm{OT = \frac{ON}{2} = 3\;\mathrm{cm}}$ $\mathrm{OP = 6\;\mathrm{cm}}$ $\mathrm{OT^2 = OR \times OP}$ $\mathrm{3^2 = OR \times 6}$ ⇒ $\mathrm{OR = \frac{9}{6} = \frac{3}{2}\;\mathrm{cm}}$ $\mathrm{PR = OP - OR}$ $ \mathrm{PR
Question : At which stage in its life cycle does the silkworm yield the fiber of commercial use:
Option 1: Larva
Option 2: Egg
Option 3: Pupa
Option 4: Imago
Correct Answer: Pupa
Solution : The correct option is Pupa.
The silkworm goes through a spectacular change inside its cocoon during the pupal stage. When the larva comes into contact with air, it secretes a sticky material called sericin, which hardens and produces the protective cocoon. The silkworm metamorphoses inside
