Question

From the digits 1,2,3,4,5 and 6 how many 3 digit Even Numbers can be formed when repetition is not allowed

Answer 1

for even number, last digit must be divisible by 2;

so in this case numbers can end with 2,4,6 and other digits can take any other not selected number

so ans = (any one digits among 2,4,6 i.e last digit)*(any one number among remaining 5 numbers)*(any one number among remaining 4 numbers)

so , ans=3*5*4=60
