Question : $\triangle DEF$ is right angled at E. EC is the altitude. CF is 18 cm and FD is 26 cm. What is the length of FE?
Option 1: $2\sqrt{13}$ cm
Option 2: $6\sqrt{13}$ cm
Option 3: $12$ cm
Option 4: $15$ cm
Correct Answer: $6\sqrt{13}$ cm
Solution : FD = 26 cm CF = 18 cm ⇒ CD = 26 – 18 = 8 cm EC2 = CD × CF = 8 × 18 = 144 ⇒ EC = $\sqrt {144}$ = 12 cm In $\triangle$ECF, $\angle$ C = $90^{\circ}$ By

Question : If the length of the side of an equilateral triangle is 8 cm, what is its area (in cm2)?
Option 1: $32\sqrt{3}$
Option 2: $16$
Option 3: $16\sqrt{3}$
Option 4: $32$
Correct Answer: $16\sqrt{3}$
Solution : The area of an equilateral triangle with side length $a$, $= \frac{\sqrt{3}}{4}a^2$ On substituting $a$ = 8 cm, The area of an equilateral triangle $= \frac{\sqrt{3}}{4} \times 8^2 = 16\sqrt{3} \text{ cm}^2$ Hence, the correct answer is $16\sqrt{3}$.
Question : Directions: Identify the figure given in the options which when put in place of the question mark (?) will logically complete the series.

Question :
Directions: In the following question you have to identify the correct response from the given premises stated according to the following symbols. Select the set of symbols that can be fitted correctly in the equation. 4....3....4 = 48
Option 1: +, +
Option 2: +, –
Option 3: ×, +
Option 4: ×, ×
Correct Answer: ×, ×
Solution : Given: 4....3....4 = 48
Let's check the options – First option: +, + ⇒ 4 + 3 + 4 = 48 On solving the L.H.S. of the equation, we get – = 4 + 3 + 4 = 11 ≠ 48 Second option: +,
Question : Directions: The second number in the given number pairs is obtained by performing certain mathematical operation(s) on the first number. The same operation(s) are followed in all the number pairs except one. Find that odd number pair. (NOTE: Operations should be performed on whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 – operations on 13 such as adding/subtracting/multiplying, etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
Option 1: 21 : 100
Option 2: 19 : 88
Option 3: 13 : 64
Option 4: 17 : 80
Correct Answer: 21 : 100
Solution : Let's check each option – First option: 21 : 100; (21 + 3) × 4 = 24 × 4 = 96 ≠ 100 Second option: 19 : 88; (19 + 3) × 4 = 22 × 4 = 88 Third option: 13 :
