@kamal_lohia why is that one of x,y,z is not greater than 3 ?
@zabeer
@zabeer it will be HCF ( a + b + 1) = 221
13*17
hcf can be 13 or 17
a+b+1 = 17 or 13
we will find out co prime pairs right ??
is the answer = 6
@shashank_prabhu part of solution is missing so unable to understand
in set 5 1st ques
26 is not possible as it will breach the first condition of 60 with each trainer
so maximum should be 23 with the same trainer as otherwise total would not be 60!
am i right ??
@shashank_prabhu like i can choose any two numbers in c(100,2) ways
out of which all the cases from 01 to 91 [ c (10,2) ] * 4 are valid ?
which gives me 180 / 450
@shashank_prabhu but doesnt that repeat possible unit digits ?
shouldnt the unit digits be 10 only?
@shashank_prabhu a little elaboration on how n(x) = 2^x ?
@shashank_prabhu can we use partition method here?
