hey guys the ans cannot be optiob B because in the second statement it is told that the third side cannot be smaller than the difference of the other two sides that means the third side can be equal or greater than the difference. but it cannot be equal that is why 2nd statement id wrong

Answer is D as in option A, 14/100 is shaded, which means 7/50 is shaded. In option B, 22/100 is shaded, which means 11/50 is shaded. In option C 29/100 is shaded. In option D, 20/100 is shaded, which means 1/5 is shaded.

Ans 3:

Class : Class 7
d) 20/100 because 20/100 is equivalent fraction of 1/5
