BPSC TGT Math & Science Mock Test - 3 - Bihar PGT/TGT/PRT MCQ

Towards indicates direction, at indicates a place and beneath indicates the position.

Answer: A. under Explanation: The correct preposition to use in this sentence is "under." This is because the preposition "under" is used to describe something that is beneath or below something else. In this case, the cat is sleeping beneath the bed. Here's a breakdown of the other prepositions and why they are not appropriate in this context: - B. above: This preposition indicates that something is higher or at a higher level than something else. In this case, it does not make sense for the cat to sleep above the bed. - C. between: This preposition is used when something is in the middle of two other things. It does not fit the context of the cat sleeping in relation to the bed. - D. over: Similar to "above," this preposition implies that something is on top of or covering something else. It does not accurately describe the cat's position in relation to the bed. So, the correct sentence is: "The cat always sleeps under my bed."

'Her' is the pronoun because it is singular. The other pronouns do not match the sentence.

Assign numbers to letter and move them like given word.

Similarly;
Arrange the given word like the bold value of CALENDAR;

Hence, option B is correct.

Total Mango trees = 40%

Remaining trees = (100 – 40 – 50)% = 10%

Hence, Option B is correct.

P is male member and married to Q.
P is husband and Q is wife.
R is brother of P.
S is the son of R.
T, who is the sister of S will be daughter of R.
Q is the daughter-in-law of U, whose husband has died means U is the mother of P.

Hence, Option C is correct.

AP: 21, 42, 63, 84, …
a = 21
d = 42 – 21 = 21
a(n) = 210
a + (n – 1) x d = 210
21 + (n – 1) x (21) = 210
21 + 21 x n – 21 = 210
21 x n = 210
n = 10

Perimeter of the wheel

Hence, Option B is correct.

The second tower is smaller than the first tower so let the height of the first tower is h So a part of it is equal to 60m so the remaining height is h-60 m
Tan 30=perpendicular/base

Thus, initial term of the A.P. is 5 and the common difference is 6.

If the outer bisectors of the angle B and angle C meet at a point O outer side of the triangle, then ∠BOC = 90° - ∠A/2 = 90° - 70°/2 = 55°

Thus, it can be expressed as product of linear factors.

Given, surface area of sphere = 221.76cm²

We know, surface area of sphere = 4πr²

⇒ 4(π)r² = 221.76

⇒ r² = 7/22​ × 221.76 × 1/4 ​= 7 × (10.08) × 1/4 ​

⇒ r = 4.2cm

Then, diameter equals 2r = 2 × 4.2 = 8.4 cm, which is true and reason is also correct.

Moreover reason is the correct explanation of assertion.

To determine the congruence rule for ΔAOC and ΔXYZ:

• Given: ∠A = ∠X


• AO = YZ (one pair of corresponding sides)


• AC = XY (another pair of corresponding sides)


• Two pairs of sides and the included angle are equal

 

Therefore, by the SAS (Side-Angle-Side) congruence rule, ΔAOC ≅ ΔXYZ.

ANSWER :- b

Solution :- Area of rec. park=(120×90)m²=10800m²

Area of rec. park excluding lawn=2950m²

Area of circular lawn=(10800 - 2950)m²

=7850m²

Let the radius be = r

7850/3.14 = 3.14r²/3.14

→2500 = r²

→√2500 = √r²

→50 = r

→r = 50

Radius = 50m

⇒   We have the sequence, 1,2,3.......n
⇒   This is an AP, with the initial term a=1 and the common difference d=1.
∴   The sum of n terms of an AP is given by,


→   Arithmetic mean of n numbers a1​,a2​,a3​,a4​,...an​ is given by the formula

One metre = 100 cm, a = 100 cm

since every year it grows 4 cm less than it did the preceding year, d = -4

Thus, it is an AP, with initial term a = 100 and d = -4

The tree will stop its growth, when nth term of the series is 0.

Nth term = a + (n - 1)d

0 = 100 + (n - 1)(-4)

0 = 100 - 4n + 4

0 = 104 -4n

4n = 104

n = 104/4

n = 26 years

Human body has different resistances, when dry, resistance is 100,000 ohms. When wet because of sweat or water, resistance is only 1,000 ohms.

The correct answer is Option B 
 
k =G*l/A      (Since, G = 1/R)
   = l/AR 
Therefore, kR = l/A 
So, l/A = kR not k/R

Nonessential amino acids can be synthesized in the body, whereas essential amino acids must be obtained in the diet. Cells in the body can provide the carbon skeleton of the nonessential amino acids.

Gain of hydrogen , electron and decrease in oxidation number is reduction

When a weak acid and a strong base combine to form a salt, the resulting compound will be basic with a pH greater than 7. The presence of a strong base in the compound contributes to its alkalinity, causing the pH to rise above the neutral value of 7.

the k is halved while the A is doubled. Hence R remain 50 Ω.

Weight of body depends on diet and habits. If somebody is not eating he will definitely lose weight as the body fat will be used for production of energy once glycogen reserve finishes.

Contributions to the success of Mendel:
1. His knowledge of biology:
- Mendel's background in biology allowed him to understand the basic principles of inheritance and genetics.
- He was knowledgeable about the reproductive processes of plants, which allowed him to perform experiments and make accurate observations.
2. Qualitative analysis of data:
- Mendel meticulously collected and analyzed data from his experiments.
- He focused on qualitative traits, such as flower color or seed texture, rather than just counting the number of offspring.
- This approach allowed him to identify distinct patterns of inheritance and formulate his laws of genetics.
3. Observation of distinct inherited traits:
- Mendel chose to study traits that were easily distinguishable and occurred in distinct forms, such as tall vs. short plants or yellow vs. green peas.
- By selecting traits with clear-cut variations, he was able to easily track their inheritance patterns and make accurate predictions.
4. Consideration of one character at a time:
- Instead of studying multiple traits simultaneously, Mendel focused on one trait, such as flower color, in each experiment.
- This allowed him to establish clear and consistent patterns of inheritance for each trait and avoid confusion or overlap between different traits.
In conclusion, Mendel's success can be attributed to his knowledge of biology, his qualitative analysis of data, his observation of distinct inherited traits, and his consideration of one character at a time. These factors enabled him to make significant discoveries in the field of genetics and lay the foundation for modern understanding of inheritance.
