Given diagram is-

No. of plants which are trees but not furniture=1

Hence, option A is the correct answer.

Only the relation between "Chef : Knife" is different, as knife is used by chef as cutlery or preparation of food. However, the other three shows a similar relationship as; first object is used either as weapon or tool to perform the second as its application. 

Therefore, option D is the odd one out. 

Hence, option D is the correct answer.

Given number = 7220x558y2 is divisible by 88.

Hence it should be divisible by 8 and 11 (88 = 8 × 11).

Divisibility of 8: Last three digits must be divisible by 8

Hence here 8y2 must be divisible by 8.
So, y = 3

Divisibility of 11: The difference of the sum of the alternate numbers is divisible by 11.

Sum of odd places = 7 + 2 + x + 5 + 3 = 17 + x

Sum of even places = 2 + 0 + 5 + 8 + 2 = 17

Difference = ( 17 + x ) – 17 ⇒ x = 0

As 0 is divisible by 11.

Value of:

5x + 5y = 5 ( 0 ) + 5 ( 3 ) = 15

Altitude in an equilateral triangle = ×side

⇒ 6√3 = side

⇒ Side = 12 cm

Area of ∆ABC = (1/2)×base×height

= (1/2)×12×6√3

= 36√3 cm²

Variance (σ²) = 2.25
Standard deviation (σ) = √2.25 = 1.5
