Answer is option (B), 8THANKS. :D

Ans 5:

Class : Class 4
Answer is option (B), because 1st Step - we cannot count the first figure triangles because these are mentioned under the (curved) or (circle) shaped. 2nd Step - In the second figure , there are 4 triangles which we can count as it is not like as metioned as first figure..... 3rd Step - In the third figure we can only see 3 triangles but then also you guys tought that answer is d but this is not the correct way! because can you all se the 2 triangles? Ok and the triangle in which the 2 triangles are mentioned is the large triangle and the correct sum is 4 4 = 8 triangles. Hence the answer is option (B). Girls are best than boys "O"!!

Class : Class 8
B

Ans 11:

Class : Class 4
4 3 = 7 not eight

Ans 12:

Class : Class 2
the first one is 4 triangles then there are 4 triangles again so 4+4=8 then plus 3 more 8+3=11 but the answer is not there so you can choose anything near to 11 wichs is12 so hence the answer is option d
