General Abilities QUESTION #7660

Meher saves Rs 4 in first week, Rs 13 in the second week, and Rs 22 in the third week. In which week will her savings reach Rs 130?

8th week
10th week✔️
12th week
None of these

Correct Answer Logic:

This is an arithmetic progression with first term $a = 4$ and common difference $d = 13 - 4 = 9$. The nth term is given by $a_n = a + (n-1)d = 4 + (n-1)9 = 130$. Solving: $9(n-1) = 126$, so $n-1 = 14$, giving $n = 15$. Wait, let me recalculate: $4 + 9(n-1) = 130$ gives $9n - 9 = 126$, so $9n = 135$ and $n = 15$. Hmm, this doesn't match options either. Actually, checking the pattern: Week 10 would be $4 + 9(9) = 4 + 81 = 85$, not 130. The answer appears to be beyond the given options.

Statistics QUESTION #1978

Question 2962

Given $n_1 = 2$ samples with replacement from population $\{4, 6, 8\}$ and $n_2 = 2$ from $\{1, 2, 3\}$, the variance of the sampling distribution of $\bar{X}_1 - \bar{X}_2$ equals:

$\dfrac{\sigma_1^2}{n_1} - \dfrac{\sigma_2^2}{n_2}$
$\dfrac{\sigma_1^2}{n_1} + \dfrac{\sigma_2^2}{n_2}$✔️
$\sigma_1^2 + \sigma_2^2$
$\dfrac{\sigma_1^2 + \sigma_2^2}{n_1 + n_2}$

Correct Answer Logic:

For independent samples, $\sigma^2_{\bar{X}_1 - \bar{X}_2} = \dfrac{\sigma_1^2}{n_1} + \dfrac{\sigma_2^2}{n_2}$. For population $\{4,6,8\}$: $\mu_1=6$, $\sigma_1^2 = \frac{8}{3}$. For $\{1,2,3\}$: $\mu_2=2$, $\sigma_2^2=\frac{2}{3}$. So variance $= \frac{8/3}{2}+\frac{2/3}{2} = \frac{4}{3}+\frac{1}{3}=\frac{5}{3}$.

Physics QUESTION #1189

Question 2965

The Ultraviolet catastrophe means:

The spectral energy concentration towards longer wavelength.
The spectral energy concentration at the middle of the spectrum.
The spectral energy concentration towards shorter wavelength side.✔️
None of these

Correct Answer Logic:

The ultraviolet catastrophe was a prediction of classical physics (Rayleigh-Jeans law) that a blackbody should radiate infinite energy at very short (ultraviolet) wavelengths: $u(\nu) \propto \nu^2 T$. The spectral energy density was predicted to increase without bound towards shorter wavelengths, which was catastrophically wrong and was resolved by Planck's quantum hypothesis.

Civil Procedure QUESTION #3718

Question 2966

A tenant signs a lease that says 'No Pets.' The landlord sees the tenant has a cat and says, 'That's a nice cat, don't worry about the rule.' Six months later, the landlord tries to evict the tenant for having the cat. Which doctrine protects the tenant?

The Parol Evidence Rule.
Waiver or Promissory Estoppel.✔️
Unconscionability.
The Statute of Frauds.

Correct Answer Logic:

By stating the tenant shouldn't worry about the rule and allowing the cat for six months, the landlord has likely waived the right to enforce the 'no pets' clause, or the tenant has a claim under promissory estoppel for relying on the landlord's statement.

Question 2972

Change the narration: He said, "May I open the window? It's rather hot in here."

He said might he open the window. It was rather hot in there.
He asked if he might open the window. He mentioned it was rather hot in there.✔️
He asked if he might open the window as it was rather hot in there?
None of these

Correct Answer Logic:

When converting direct speech requesting permission to indirect speech, 'may' changes to 'might', and the reporting verb 'said' changes to 'asked'. The statement about temperature is reported separately using 'mentioned' or 'said'. Both parts need to be connected appropriately.
