We note from the diagram below no. of tea drinkers =17+a+b+c+d+e+f=36. Hence a+b+c+d+e+f=36−17=19. Also cocoa and chocolate =d+e+h+i=7.
Hence a+b+c+d+h≤19+7=26. Also cocoa drinkers 20+b+d+g+h+i+e=27⇒b+d+g+h+i+e=7. Hence
b+g+(d+e+h+i)=7⇒b+g+7=7⇒b=g=0. Hence a+b+c+d+h+g≤26+0=26. But no of coffee drinkers =60. Whereas no. of coffee drinkers is 30+a+b+c+d+g+h≤26+30=56⇒⇐.
