Sir, 1:52:00 .. Us Question mai a=5 b=10 c=15 d = 20 e= 25 f= 30 xRy => (5,10) R ( 15,20 ) => 5*20 - 10*15 = 100 - 150 = 5m => -50 = 5m ( Divisible by 5 ) yRz => (15,20 ) R (25,30 ) => 15*30 - 20*25 = 450 - 500 = 5m => -50=5m ( Divisible by 5 ) xRz => (5,10 ) R (25,30 ) => 5*30 - 10*25 => 150 - 250 = 5m => -100 = 5m ( Divisible by 5 ) Idhar sabhi true ho rahe hai tho phir Transitive haina??
