हल-क्षेत्र \(x\geq 1\), \(y\geq 1\), \(x+y\leq 5\) में पूर्णांक निर्देशांक वाले कितने बिंदु हैं?

How many points with integer coordinates are in the region \(x\geq 1\), \(y\geq 1\), and \(x+y\leq 5\)?

Explanation opens after your attempt
Correct Answer

A. (10)

Step 1

Concept

For (x=1,2,3,4), the possible counts are (4,3,2,1). Hence the total is (10) points.

Step 2

Why this answer is correct

The correct answer is A. (10). For (x=1,2,3,4), the possible counts are (4,3,2,1). Hence the total is (10) points.

Step 3

Exam Tip

(x=1,2,3,4) के लिए क्रमशः (4,3,2,1) मान मिलते हैं। इसलिए कुल (10) बिंदु हैं।
