- case 1 : there are 5 no.s of 1 digits (i.e 5)
case 2 : there are 20 no.s of 2 digits (i.e 5*4=20)
case 3 : there are 60 no.s of 3 digits (i.e 5*4*3 = 60)
case 4 : there are 120 no.s of 4 digits (i.e 5*4*3*2=120)
case 5 : there are 120 no.s of 5 digits (i.e 5*4*3*2*1=120 )
hence total no.s are 5+20+60+120+120 = 325 - 11 years agoHelpfull: Yes(26) No(2)
