A broken clock loses four minutes every hour . If the broken clock and a normal clock are both set at noon what time will the normal clock say when the broken clock reads 2:20pm

Time in normal clock = 2:30 PM

Step-by-step explanation:

Given:

Clock losses 4 min per hour

Total time = 2:20 Pm

Find:

Time in normal clock

Computation:

Total time = 2:20 = 2.333 hour

Total time losses = 2.333 x 4 min = 9.32 minutes (Approx)

Time in normal clock = 2:20 + 9.32 minutes (Approx)

Time in normal clock = 2:29.32 0r 2:30 PM

introduction, methodology, results, discussion

step-by-step explanation:

an observational study is one which consists of actual observation to record data and then analyse the data.

there are a number of factors that should be analyzed before starting an observational study.

i) introduction:   this should be analysed to check whether the purpose of the study is correctly established and the data recorded are appropriate for the study

methodology:   the method of collecting the data, such as whether randomly selected, and whether sample size matches with the population to be studied, whether questions asked are easy to answer by common men, etc.

results: then results such as summary of data with comments should be studied thoroughly

discussion:   the last is the discussion, this can be either by management people or persons who are all interested , etc.

correct answer is b. 27/8
