The noise level of 10 dB is how many times more powerful than the noise level of 1 dB

The noise level of 10 dB is how many times more powerful than the noise level of 1 dB Correct Answer 10 times

Noise level in dB = 10Log10 (Noise in watts)

10 dB = 10Log10 (Noise in watts)

Noise in watts for 10 dB = 101 = 10 Watts …(1)

1dB = 10 Log10 (Noise in watts)

Noise in watts for 1 dB = 100.1 = 1.26….(2)

P1/P2 = 10/1.26 = 7.94 W

Best suitable option is option b

In each question below is given a statement numbered I, II and III. An assumption is something supposed or taken for granted. You have to consider the following assumption and decide which of the assumption is implicit in the statement. Statement: About a year ago, Prime Minister Narendra Modi had told the world that the signature of a chartered accountant on financial statements was, perhaps, more powerful than even one of his own. ‘Just like doctors don’t want people to be ill to get more business, chartered accountants, too, need to safeguard the society’s economic health. Your signature is more powerful than the PM’s, and the government also believes the accounts signed by you’, Modi had said.  Assumptions: I. The CA community, however, may not have woken up to the value of the initials they put on financial statements. Last year has been more of a challenge for the community’s reputation, with banking frauds, asset quality divergences and mid-term auditor resignations dominating the headlines.  II. There cannot be a situation where there will be 100% agreement on everything. You may have rules but still judgmental factors in credit, asset recognition come in. The approach is that as soon as the asset is stretched, banks have to recognise the problem.  III. But even basic logic just went out of the window and banks together kept dishing out loans to such companies even when their annual turnover was half of the total debt.
