The number of positive integral solution of the equation is
1800
1600
1400
none of these
Using prime factorization of 1050 , we can write the given equation as
We can assign 2, 3 or 7 to any of 5 variables. We can assign entire to just one variable in 5 ways or can assign
to two variables in
ways. Thus,
can be assigned in
Thus, the required number of solutions is .
