Question : Directions: Which of the following letter clusters should replace # and % so that the pattern and relationship followed between the letter-cluster pair on the left side of :: is the same as that on the right side of ::? # : CLQ :: NDK : %
Option 1: # = AJS, % = MAM
Option 2: # = AOO, % = PAM
Option 3: # = EIT, % = QBN
Option 4: # = DIS, % = PBN
Correct Answer: # = AOO, % = PAM
Solution : Given: # : CLQ :: NDK : %
Let's check the options – First option: # = AJS, % = MAM AJS : CLQ→A + 2 = C; J + 2 = L; S – 2 = Q NDK :
Question : In the given figure, if KI = IT and EK = ET, then $\angle$ TEI =________.
Option 1: 75°
Option 2: 125°
Option 3: 105°
Option 4: 150°
Correct Answer: 105°
Solution : KI = IT and EK = ET $\angle$ KET = 150° In $\triangle$ KEI and $\triangle$ TEI, KI = IT [Given] EK = ET [Given] EI = EI [Common] So, $\triangle$ KEI $\cong$ $\triangle$ TEI, ⇒ $\angle$ KEI = $\angle$ TEI Now, $\angle$ KET +
Question :
Directions: In the following question, you have to identify the correct response from the given premises stated according to the following symbols: If × means –; – means ×; + means ÷ and ÷ means +; then (15 – 10) ÷ (130 + 10) × 50 = ?
Option 1: 1800
Option 2: 113
Option 3: 2000
Option 4: 123
Correct Answer: 113
Solution : Given: × means –; – means ×; + means ÷ and ÷ means +. (15 – 10) ÷ (130 + 10) × 50 = ?
After replacing the symbols, the equation becomes – = (15 × 10) + (130 ÷ 10) – 50 = 150
Question : A1, A2, and A3 alone can complete a piece of work in 12 hours, 24 hours, and 16 hours respectively. Working together, in how much time will they complete the same work?
Option 1: 5 hours 30 minutes
Option 2: 5 hours 20 minutes
Option 3: 4 hours 20 minutes
Option 4: 3 hours 30 minutes
Correct Answer: 5 hours 20 minutes
Solution : Time taken by A1 to do the work = 12 hours ⇒ 1 day's work of A1 = $\frac{1}{12}$ Time taken by A2 to do the work = 24 hours ⇒ 1 day's work of A2 = $\frac{1}{24}$
Question : Direct conversion of solar energy with the use of a photo voltaic cell results in the production of
Option 1: Optical energy
Option 2: Electrical energy
Option 3: Thermal energy
Option 4: Mechanial energy
Correct Answer: Electrical energy
Solution : The correct option is electrical energy.
The photovoltaic effect is a mechanism used by photovoltaic cells, also referred to as solar cells, to transform light energy from the sun directly into electrical energy. When photons, the light particles hit a solar cell's surface, their
Question : Directions: In a code language, SLAIN is written as PKCNU and DENT is written as VPGF. How will CUBOID be written in that language?
Option 1: FKQDWE
Option 2: FJQDWE
Option 3: FKQDVF
Option 4: EWDPKE
Correct Answer: FKQDWE
Solution : Given: SLAIN is written as PKCNU and DENT is written as VPGF.
Follow the pattern to obtain the required code – Thus, SLAIN is coded as PKCNU. And, DENT is written as VPGF. Thus, DENT is coded as VPGF. Similarly, follow the same pattern for
