Question 1135440: Numbers are formed using the digits 4,5,6,7 and 8 with no digit being used more than once. How many odd number are less than 700?
I got the answer as 15 but was told the answer is 25. This is my working
First digit is an even number which is either 4 or 6 and last digit is either 5 or 7
thus possible combination is 2*3(ie remaining numbers)*2(ie. possible combination of last digit) = 12
First digit is an odd number ie 5 and last digit is just 7 therefore
possible combination is 1*3*1 = 3
Therefore the answer is 12+3 = 15 possible ways. Is this correct? Thanks
