x = 39 %

Step-by-step explanation:

GIVEN :-

72% of the Indians like tea

&

67% like coffee

TO FIND :-

% of the Indians like both tea and coffee.

SOLUTION :-

since,x% of Indian like both coffee and tea.

so,

Let the no. of people be 100x

its given that 72% of Indians like tea

so,

➝$\sf{\dfrac{72}{\cancel{100}}\:\times\:\cancel{100}x}$

➝$\sf{72\:\times\:x}$

➝$\sf{72x}$

&

67% of Indians like coffee

so,

➝$\sf{\dfrac{67}{\cancel{100}}\:\times\:\cancel{100}x}$

➝$\sf{67\:\times\:x}$

➝$\sf{67x}$

NOW,

For the no. of indians who likes both ,

➝$\sf{eq^n\:will\:be\::-}$

➝$\sf{72x\:+\:67x\:-\:100x}$

➝$\sf{139x\:-\:100x}$

➝$\sf{39x}$

So,the percentage of Indian like both tea and coffee,

➝$\sf{\dfrac{39x}{\cancel{100x}}\:\times\:\cancel{100}}$

➝$\sf{39\%}$
