I think 4th answer is only one pair as (0,0) is not a integer pair.

1. GUDURU VANAJA

In a triangle,there is a property..that is sum of any two sides length of triangle is greater than the third side.
That’s why here perimeter is 14,hence possible sides are (4,4,6),(4,5,5),(6,5,3),(6,6,2)

4. Nitesh

In question no. 2
z and X can take the value 8 and 1 respectively
i.e 891-198=693 i.e divisible by 7

hence a) 100<A<299 is correct
