A man must possesses some qualities. First, he must trust his friend. Only then he can open himself up to him. Secondly a friend should not always find faults with his friend.

        PPF and MRT We can measure MRT on the PPF. For example, MRT between the possibilities D and E is equal to DH/HE and between E and F, it is equal to EI/IF and so on.We know, PPF is concave shaped curve. The slope of PPF is a measure of the MRT. Since the slope of a concave curve increases as we move downwards along the curve, the MRT also rises as we move downwards along the curve. हम PPF पर MRT माप सकते हैं। उदाहरण के लिए, संभावनाओं D और E के बीच MRT DH/HE के बराबर है और E और Fके बीच, यह EI/EF के बराबर है और इसी तरह।हम जानते हैं, PPFअवतल आकार का वक्र है। PPFका ढलान MRT का माप है। चूँकि जैसे-जैसे हम वक्र के साथ नीचे की ओर बढ़ते हैं, अवतल वक्र की ढलान बढ़ती जाती है, जैसे-जैसे हम वक्र के साथ नीचे की ओर बढ़ते हैं, MRT भी बढ़ती जाती है।                   You tube Video
