दिले:

1) 62% अधिकारी वक्तशीर (P) आहेत 

P = a + g + d + f = 62%

2) 58% अधिकारी प्रामाणिक आहेत (H)

H = b + g + d + e = 58%

3) 70% अधिकारी धाडसी आहेत (B)

B = c + f + d + e = 70%

4) 38% अधिकारी वक्तशीर (P) आणि प्रामाणिक (H) आहेत

g + d = 38%

5) 48% प्रामाणिक (H) आणि शूर (B) आहेत 

e + d = 48%

6) 36% वक्तशीर (P) आणि शूर (B) आहेत

f + d = 36%

आपल्याला माहित आहे की,

100 % = [P + H + B] – [(g +d) + (e +d) + (f +d)] + d

100% = [62% + 58% + 70%] – [(38%) + (48%) + (36%)] + d

100% = 190% - 122% + d

100% = 68% + d

d = 100% - 68%

d = 32%

त्यामुळे32% टक्के अधिकारी वक्तशीर (P), प्रामाणिक (H) आणि धाडसी (B) आहेत.
