X is a 5 digit no. such that each digit is either nonzero or even and there is only one single repetition allowed.If the repeated digits are adjacent and X is divisible by 4. Then how many values of X are possible ?
uys koi general appraoch bata sakta hai for series where the difference between adjacent two numbers is in A.P... I mean to say sum of first 20 terms of 3,7,12,18 and so on...
for how many ordered triplet (a,b,c) of positive integers less than 10 is the product of a b c divisible by 20.
if a,b,c are all positive integers 1/a + 1/b +1/c + 24/abc=1
find the sum of all the values of abc.
