2251.	Both x and y vary directly with each other and when x = 20, y = 28. Which of the following is not a possible pair of corresponding values?1. 25 ∶ 35 2. 35 ∶ 253. 35 ∶ 494. 15 ∶ 21
Answer» Correct Answer - Option 2 : 35 ∶ 25 Given: Both x and y vary directly with each other and when x = 20, y = 28. Concept Used: Concept of ratio and proportion Calculation: Both x and y vary directly with each other and when x = 20, y = 28 That means x and y are directly proportional The ratio of x and y is x : y = 20 : 28 ⇒ x : y = 5 : 7 Now from the given options get, 25 : 35 ⇒ 5 : 7 35 : 25 ⇒ 7 : 5 35 : 49 ⇒ 5 : 7 15 : 21 ⇒ 5 : 7 Except the 2nd option all are in similar form that means our required answer is the 2nd option i.e. 35 : 25 ∴ 35 : 25 is not a possible pair of corresponding values.

2251.

Both x and y vary directly with each other and when x = 20, y = 28. Which of the following is not a possible pair of corresponding values?1. 25 ∶ 35 2. 35 ∶ 253. 35 ∶ 494. 15 ∶ 21

Answer» Correct Answer - Option 2 : 35 ∶ 25

Given:

Both x and y vary directly with each other and when x = 20, y = 28.

Concept Used:

Concept of ratio and proportion

Calculation:

Both x and y vary directly with each other and when x = 20, y = 28

That means x and y are directly proportional

The ratio of x and y is x : y = 20 : 28

⇒ x : y = 5 : 7

Now from the given options get,

25 : 35 ⇒ 5 : 7

35 : 25 ⇒ 7 : 5

35 : 49 ⇒ 5 : 7

15 : 21 ⇒ 5 : 7

Except the 2nd option all are in similar form that means our required answer is the 2nd option i.e. 35 : 25

∴ 35 : 25 is not a possible pair of corresponding values.

Answer»

Given A = {10, 20, 30, 40, 50, 60, 70}

B = {50, 60, 70, 80}

C = {30, 40, 90}

∴ A ∪ B = {10, 20, 30, 40, 50, 60, 70, 80}

A ∩ C = {30, 40}

and B ∩ C = ϕ

Now, (A ∪ B) ∩ C = {30, 40}.

And (A ∩ C) ∪ (B ∩ C) = {30, 40} ∪ ϕ = {30, 40}

Therefore, (A ∩ B) ∪ C = (A ∩ C) ∪ (B ∩ C).

2273.

Solve the problem:\(3 \frac{4}{5} + 2 \frac{3}{10} + 1 \frac{1}{15}\)

Answer»

First convert each mixed fraction into improper fraction.

We get,

\(\Rightarrow 3 \frac{4}{5} = \frac{19}{5}\)

\(\Rightarrow 2 \frac{3}{10} = \frac{23}{10}\)

\(\Rightarrow 1 \frac{1}{15} = \frac{16}{15}\)

Then,

\(\frac{19}{5} + \frac{23}{10} + \frac{16}{15}\)

LCM of 5,10,15 = 30

Now,let us change each of the given fraction into an equivalent fraction having 30 as the denominator

\(\Rightarrow \frac{19}{5} \times \frac{6}{6} = \frac{114}{30}\)

\(\Rightarrow \frac{23}{10} \times \frac{3}{3} = \frac{69}{30}\)

\(\Rightarrow \frac{16}{15} \times \frac{2}{2} = \frac{32}{30}\)

Now,

\(= \frac{114}{30} + \frac{69}{30} + \frac{32}{30}\)

\(= \frac{114+69+32}{30}\)

\(=\frac{215}{30}\)

\(= 7 \frac{1}{5}\)

Answer» Since the bag has 20 tickets, total number of cases n = 20 Let A: getting a multiple of 2 B: getting a multiple of 5 Event A has 10 favourable outcomes A = {2, 4, 6, 8, 10, 12, 14, 16, 18, 20} ∴ P(A) = \(\frac{10}{20} =\frac{1}{2}\) Event B has four favourable outcomes B = {5, 10, 15, 20) ∴ P(B) = \(\frac{4}{20}\) A ∩ B = {10,20] ∴ P(A ∩ B) = \(\frac{2}{20}\) ∴ P(multiple of 2 or 5 ) = P(A ∪ B) =P(A) + P(B) – P(A ∩ B) = \(\frac{10}{20} + \frac{4}{20} - \frac{2}{20} = \frac{12}{20} = \frac{3}{5}\)

One ticket is drawn at random from a bag containing 20 tickets numbered 1 to 20. Find the probability that it is a multiple of 2 or 5,

Answer»

Since the bag has 20 tickets, total number of cases n = 20

Let A: getting a multiple of 2

B: getting a multiple of 5

Event A has 10 favourable outcomes

A = {2, 4, 6, 8, 10, 12, 14, 16, 18, 20}

∴ P(A) = \(\frac{10}{20} =\frac{1}{2}\)

Event B has four favourable outcomes

B = {5, 10, 15, 20)

∴ P(B) = \(\frac{4}{20}\)

A ∩ B = {10,20]

∴ P(A ∩ B) = \(\frac{2}{20}\)

∴ P(multiple of 2 or 5 ) = P(A ∪ B) =P(A) + P(B) – P(A ∩ B)

= \(\frac{10}{20} + \frac{4}{20} - \frac{2}{20} = \frac{12}{20} = \frac{3}{5}\)

Answer» Ordinary rubber is an insulator. But the special rubber tyres of aircrafts are made slightly conducting. This is because during landing or takeoff, the tyres of aircrafts get charged due to friction between tyres and fround. In case, the tyres are slightly conducting, the charges developed on the tyres will not stay on them and find its way to earth.

A bullet of mass 0.02 kg strikes a metal plate of thickness 10 cm with a velocity of 400 m/s and emerge from it with a velocity of 250 m/s. Find the average resistance force offered by the plate to the motion of bullet.

Answer»

We know that,

v² = u² + 2as

a = \(\cfrac{v^2-u^2}{2s}\)

a = \(\cfrac{(250)^2-(400)^2}{2\times0.1}\)

a = \(\cfrac{62500-160000}{2\times0.1}\)

a = \(\cfrac{-97500}{0.2}\)

a = -487500 m/s²

F = ma

F = 0.02 x - 487500

F = -9750 N

At least two of the spheres are positively charged. Which sphere, if any, could be negatively charged? A. sphere AB. sphere BC. sphere CD. no sphere
Answer» Correct Answer - A It can be seen from the diagram that only the sphere B and C repel. Hence they both must e of same type. According to the fact that at least two spheres are positively charged, therefore both spheres should be positively charged. Since attraction occurs for two remaining pairs it can be concluded that the sphere A is negatively charged.
