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
Question : Study the given pie chart and answer the question that follows.
The pie chart represents the marks (out of 100) obtained by Shweta in different subjects - Hindi, English, Maths, Science, Social Science (S.S.) and Commerce in her class examination. The marks obtained in English and S.S. are what percent less than the marks obtained in Hindi and Maths?
The marks obtained in English and S.S. are what percent less than the marks obtained in Hindi and Maths?
Option 1: $30 \frac{1}{8} \%$
Option 2: $31 \frac{5}{8} \%$
Option 3: $30 \frac{5}{8} \%$
Option 4: $31 \frac{1}{8} \%$
Correct Answer: $30 \frac{5}{8} \%$
Solution : Share of marks obtained in English = $52^{\circ}$ Share of marks obtained in S.S. = $59^{\circ}$ Share of total marks obtained in English and S.S = $52^{\circ}$+$59^{\circ}$ = $111^{\circ}$------------(i) Share of marks obtained in Hindi = $72^{\circ}$ Share of marks obtained in Maths
Question : In triangle MNO, AB is parallel NO and MA = 2.5, AN = 7.5, MB = 2.2, find the value of BO.
Option 1: 6.6
Option 2: 8.2
Option 3: 5.4
Option 4: 4.8
Correct Answer: 6.6
Solution : Given: In triangle MNO, AB is parallel NO and MA = 2.5, AN = 7.5, MB = 2.2 Here, triangles MNO and MAB are similar because angle M in triangle MNO is equal to angle M in triangle MAB. So, $\frac{MA}{MN}=\frac{MB}{MO}$ ⇒ $\frac{2.5}{2.5+7.5}=\frac{2.2}{MO}$ $\therefore MO=8.8$
