B.2
C.3
D.4
E.5
CarcassI believe the Qs should be - 4 of them study both the cooking and yoga
ONLY and How many people study both cooking and weaving
ONLYOther wise we can have a different answers.
Refer to the figures below:
Case I: 4 of them study both the cooking and yoga ONLY
Cooking = Cooking only + Cooking and Yoga only + Cooking and Weaving only + All three
10 = 3 + 4 + Cooking and Weaving only + 2
Cooking and Weaving only = 1
Cooking and Weaving = All three + Cooking and Weaving only = 2 + 1 = 3
Case II: 4 of them study both the cooking and yoga
Cooking = Cooking only + Cooking and Yoga only + Cooking and Weaving only + All three
10 = 3 + 2 + Cooking and Weaving only + 2
Cooking and Weaving only = 3
Cooking and Weaving = All three + Cooking and Weaving only = 2 + 3 = 5
