Question

Find the odd one out. (1) (16, 30, 34) (2) (11, 40, 41) (3) (20, 21, 29) (4) (11, 60, 61)

Answer 1

HI GUYS THE FIRST ANS IS 16 BECAUSE IT NOT IN 3 TEN SECOND ANS IS 40 BECAUSE IT IS EVEN THIRD ANS IS 20 BECAUSE IT IS EVEN AND FOURTH ANS IS 60 BECAUSE IT IS EVEN

Answer 2

Dear Student,

Please follow the solution to the above given query:

Let us check if they satisfy pythagoras theorem:

Perpendicular, Base, Hypotenuse

a. 16, 30, 34

b. 11, 40, 41

c. 20, 21, 29

d. 11, 60, 61

For Pythagoras theorem,

We will check the same for pythagoras theorem.P2+B2=H2a) P2+B2=162+302=256+900=1156H2=342=1156Thus, P2+B2=H2b) P2+B2=112+402=121+1600=1621H2=412=1681Thus, P2+B2≠H2Similarly, we can check for option (c) and (d), they will satisfyPythagoras theorem.Thus, option (b) is the odd one out.

a) P2+B2=162+302=256+900=1156H2=342=1156Thus, P2+B2=H2b) P2+B2=112+402=121+1600=1721H2=412=1681Thus, P2+B2≠H2Similarly, you can check for other two options as they will satisfy pythgoras theorem.Thus, the odd one out is option (b) only.
