0 votes 0 votes since according to pigeon hole principle if there are n pigeons and m holes and n>m then atleast a hole will have floor((n-1)/m)+1 pigeons. so n=50 m=7 floor((50-1)/7)+1=8 so atleast a hole will have 8 pigeons but not 9 pigeons so c is the answer. neelesh bhakt answered Jan 29, 2018 • edited Jan 29, 2018 by neelesh bhakt neelesh bhakt comment Share Follow See all 3 Comments See all 3 3 Comments reply Pawan Kumar 2 commented Jan 29, 2018 reply Follow Share yeah but why b is true ? 0 votes 0 votes neelesh bhakt commented Jan 29, 2018 reply Follow Share Obviously if there are atleast 8 so 7 can also be there but not more than 8 0 votes 0 votes Pawan Kumar 2 commented Jan 29, 2018 reply Follow Share if at least 8 are there how come 7 be true?.... at least 8 means...8,9,10.......... isnt it 0 votes 0 votes Please log in or register to add a comment.
