Whole question is wrong. The solution is also wrong. The 'squares' in the question and the solution has to be changed to 'triangles. The only thing which was right is the diagram in the solution.

Ans 14:

Class : Class 6
The correct answer is C because one is the outer square, then there are 4 squares inside it and one square is tilted so that will also count.

Ans 15:

Class : Class 5
Correct answer is B

Ans 16:

Class : Class 4
It should be 6 as the first one is the outer square(biggest one) and there are 4 small squares inside it, which makes 5 squares. There is also one square inside the figure which is tilted. It looks like a rhombus but isn't a rhombus because a rhombus doesn't have 4 angles measuring 90 degrees.

Ans 17:

Class : Class 6

Ans 18:

Class : Class 4
there are 10 triangles:A,B,C,D,E,F,G,H,BC AND GH

Ans 19:

Class : Class 7
yes,b is the right answer. we should just turn the diamond little bit. it will become square. and the other 5 squares.

The correct answer should be Option B. By Ankush

Ans 5:

Class : Class 8
B AS we convert mixed to improper fraction so 4 1/2 = 2 x 4 1 /2 = 9/2 2 1/8 = 8 x 2 1 / 8 = 17/8 Then we find equivalent fractions 9/2 = 9 x 4 / 2 x 4 = 36 / 8 and 17 / 8 will remain same as we know. Now we do subtraction. 36 / 8 - 17 / 8 = 36 - 17 / 8 = 19 / 8 = 19 divided by 8= Quotient=2, Remainder=3 so 2 3/8

Ans 6:

Class : Class 7
b because if we divide the into 2 part i.e 4 and 1/2 and 2 and 1/8 means 4-2 whloes is 2 1/2 and 1/8 way 1/2=2/4=4/8-1/8=3/8 hence ans 2 wholes and 3/8
