A group of people participate in some curriculum, 20 of them practice Yoga, 10 study cooking, 12 study weaving, 3 of them study cooking only, 4 of them study both the cooking and yoga, 2 of them participate all curriculums. How many people study both cooking and weaving?
A.1 B.2 C.3 D.4 E.5
IMO. Answer should be E.
4 of them who study Cooking and yoga includes 2 who participate in all three.
So who ONLY study cooking and yoga is 2.
From that who study ONLY cooking and weaving are 10- ( ONLY study cooking and yoga)- (participate in all three.) - (study cooking only)
= 10 -2-2-3 = 3
But what here asked is people who study both cooking and weaving = (ONLY cooking and weaving) + (participate in all three) = 3 + 2 = 5
Correct me if I am wrong.
