Question

A survey shows that 67% of the people like product P1 whereas 73% like product P2. If x% of the people like both the products P1 and P2, find the value of x​

Answer 1

Step-by-step explanation:

LET 100% BE THE UNIVERSE OF THE GIVEN SET

A.T.Q

n(a)=67%

n(b)=73%

n(a intersection b)=x%

to find :- x

solution:-

100%=(67%+73%)-x%

100% = (140)%-x%

100%-140%= -x%

(100-140)%= -x%

=> -40% = -x%

= 40% = x%

percent get cancel with other percent

therefore, x =40
