Suppose a triangle is formed by and the coordinate axes. Then the number of points where and are natural numbers, lying inside the triangle is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(A)
Step-by-step Solution
Detailed explanation
Plotting the diagram of the given value we have, Triangle formed will have vertices as O0,0, A10,0 and B0,10 If x=1, Point on the hypotenuse ≡1,9 So, number of integral points lying inside triangle when x=1 is 8 i.e 1,1,1,2⋯1,8 Similarly, when x=2, number of…
