Question : Directions: The present age of A is two times the present age of B. After 8 years, B's age will be four times C's present age. If 9 years ago, C celebrated his fifth birthday, then what is the present age (in years) of A?
Option 1: 88
Option 2: 96
Option 3: 92
Option 4: 84
Correct Answer: 96
Solution : Let the present age of C be x years. Since 9 years ago, C celebrated his 5th birthday ⇒ x – 9 = 5 ⇒ x = 5 + 9 ⇒ x = 14 years So, C's present age is 14 years. Also, after 8
Question : Directions: Which of the following terms will replace the question mark (?) in the given series? PGLT, RHNU, TIPV, VJRW, ?
Option 1: WKUX

Option 3: WXKT
Option 4: XKTX
Correct Answer: XKTX
Solution : Given: PGLT, RHNU, TIPV, VJRW, ?
In the above-given series, add 2 and 1 alternately to the place value of the letters of the previous term to get the next term. PGLT→P + 2 = R; G + 1 = H; L + 2 =

Solution : The correct option is - Aedes.
Through the bite of an infected Aedes species mosquito, the zika virus is spread.
These mosquitoes are also responsible for the dengue and chikungunya virus transmission.
Question : If $b=5$, determine the value of an expression $\left(\frac{5}{b}+5b\right)\left(\frac{25}{b^{2}}-25+25 b^2\right)$ using an identity.
Option 1: 25,726
Option 2: 15,626
Option 3: 15,438
Option 4: 25,636
Correct Answer: 15,626
Solution : $(\frac{5}{b}+5 b)(\frac{25}{b^{2}}-25+25 b^2)$ This equation is in the form of $(x+y)(x^{2}–xy+y^{2})$ We know $x^{3}+y^{3}=(x+y)(x^{2}–xy+y^{2})$ So, $x = \frac{5}{b}$ and $y = 5b$ Putting the value of $b = 5$ we get, $x^{3}+y^{3} = (\frac{5}{5})^{3} + (5\times 5)^{3}$ Or, $x^{3}+y^{3}= 1+15625 = 15626$ Hence, the correct

Question : Directions: Select the set in which the numbers are related in the same way as the numbers of the following sets. (NOTE: Operations should be performed on the 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.) (82, 35, 78) (18, 27, 30)
Option 1: (21, 27, 24)
Option 2: (15, 36, 38)
Option 3: (27, 33, 40)
Option 4: (20, 25, 32)
Correct Answer: (27, 33, 40)
Solution : Given: (82, 35, 78); (18, 27, 30)
In the given sets, divide the sum of the first two numbers by 3 and then multiply by 2 to get the third number. (82, 35, 78)→{(82 + 35) ÷ 3} × 2 = {117 ÷
Question : Steel is used to make a hemispherical bowl that is 0.37 cm thick. The bowl's inner radius is 6 cm. Find the bowl's outside curved surface area (take $\pi=\frac{22}{7}$).
Option 1: 532 cm2
Option 2: 255.0548 cm2
Option 3: 484 cm2
Option 4: 523.4107 cm2
Correct Answer: 255.0548 cm2
Solution : Given: Steel is used to make a hemispherical bowl that is 0.37 cm thick. The bowl's inner radius is 6 cm. According to the formula, ⇒ Outer radius = 6 + 0.37 = 6.37 cm $\therefore$ Curved surface area = 2 × 227
Question : If a speed of rotation of the earth increases, the weight of the body
Option 1:
Option 2:
Option 3:
Option 4:
Correct Answer:
Solution : The correct answer is decreases.
According to centrifugal acceleration formulae, as angular speed increases, the net acceleration due to gravity decreases. As a result, the weight will reduce. Alternatively, as the rotational speed of earth increases, the gravity at equator decreases and as a result the
