Question

a lecture period (50min) are close to one microcentury then tell how ong is microcentury in minute

Answer 1

1 century = 100 years = 100 * 365.25 days = 36525 days = 36525 *24 *60 min = 52596000 minutes

Hence

1 micro century = 52596000* 10^-6 = 52.596 minutes

Hence

Percentage difference = (52.596 -50)* 100/ 52.596

= 4.9 %

Answer 2

Solution :-

$( \frac{ {10 }^{ - 6} century}{1} ) \times ( \frac{100 \: years \: }{1century} ) \times ( \frac{365 \: days \: }{1 \: year} ) \\ (\frac{24hour}{1day} ) \times ( \frac{60 \: min \: }{1 \: hour} ) = 52.56 minutes \\ use \: the \: following \: conversion \: factor \: for \: a \: = \\ micro \: = {10}^{ - 6} \\ 1century = 100years \\ 365days \: = 1 \: year \: \\ 24hour \: = 1day \\ 60min = 1hour \\ hence \\ percentage difference = \\ \frac{52.56 - 50}{52.56} \times 100 = 4.856\% \: apporx \\ \\ [i \: hope \: its \: help \: you \: )]$]
