00:00 - 00:59 | ab reads a book everyday some pages in the morning and some in the evening he reached 23 pages every morning and 31 pages every evening the number of pages completed by app after some number of days can be written as a function of number of pages read in evening if the number of days is represented by N the number of pages read in the morning by N and the number of pages read in the evening by me with your of the following is the number of days for which app read read the book it is known that I breathe in morning he does not read in evening and vice versa so the question clearly states that if he reads Hindi morning then he will not read in that same evening so he will read either in morning or in evening |

01:00 - 01:59 | so we can say the total number of days should be equal to total number of days he read should be equal to number of days he read in morning number of days he read in morning + number of days he read in evening we are saying so because the question clearly states that if he is in morning then he won't read in evening and if periods in evening then he won't be reading that same morning therefore we can say that on some days he read only in the morning and in some days he read only in the evening so the total number of days that he would be reading should be some of both of these since both of them are mutually exclusive is the total should be addition of both of these |

02:00 - 02:59 | bartan dhona band kar sakti ho to Kyon D question sweet that the total number of days he has read is being represented by N so we can call this as in as mentioned in the question to N should be equal to number of days he read in morning + number of days he read in now we will consider both this term and disturb individually number of days he read in morning the question says that he reads 23 pages every morning that is if he reads in a particular morning he would be reading 23 pages and the question also states that the total number of pages that he read in the morning is called M so to find this we can say that I'm |

03:00 - 03:59 | should be equal to 20 3 into number of days we are saying so because M is the total number of pages that he has read in the morning Per morning he reads 23 pages so we can say total number of pages he read in morning 23 is the number of pages that is being read for morning is every morning 23 into number of days this the total number of pages that he read in morning has clearly been given as M2 from here that number of days will be equal to M / 23 therefore we have found out that the number of days that he read in morning equals to M / 23 similarly for number of days he read in evening |

04:00 - 04:59 | total number of pages evening should be equal to 31 into number of days that he read in evening we are saying so because the question clearly states that he reads 31 pages every evening therefore the total number of pages that he read throughout all the evenings should be equal to 31 into number of days because 31 is the number of pages that is being read per day in evening so we can say number of days read in evening should be equal to total number of pages that he read in evening that according to question = 2 / 31 this value is given according to the question to be so we are getting number of days |

05:00 - 05:59 | he write in evening should be equal to 2 / 31 now the first equation that we had written was the total number of days he read equals to number of days he read in morning + number of days he riding evening because he's either in the morning or in the evening to the total number of days that he read which is what we have to find out is in according to the question so according to this equation in should be equal to number of days he died in the morning this we have derived just now so we can say that number of days that he read in morning we have derived to BM / 23 so will substituted here and / 23 + number of days that he read in evening we have also found out this just now |

06:00 - 06:59 | so we see that number of days that he read in the evening we have derived to be eat divided by 30 so the total would be m b 23 + 31 now we try to check the option of this question we see that option number see perfectly matches are calculation in C is the final answer |
