Correct Answer: 40.5°

Solution : According to the question
$\angle P$ = 4 × $\angle R$
The sum of the opposite angles in a cyclic quadrilateral is 180°.
So, $\angle P$ + $\angle R$ = 180°
⇒ 4$\angle R$ + $\angle R$ = 180°
⇒ $\angle R$ = 36°
Now,

Correct Answer: 40

Solution : Given that the number is 216.
$216 = 2^3 \times 3^3$
To find the odd factors, we simply remove the higher power terms of 2.
$\therefore$ Sum of odd divisors = $(2^0) (3^0 + 3^1 + 3^2 + 3^3)= 1 \times 40 = 40$
Hence,

Correct Answer: 72

Solution : Given numbers:
8, 12, and 18
We can write,
8 = 2 × 2 × 2
12 = 2 × 2 × 3
18 = 2 × 3 × 3
⇒ LCM = 2 × 2 × 2 × 3 × 3
= 72
Hence,

Correct Answer: 18

Solution : Given: 9 + 3 ÷ 4 – 8 × 2
Changing the signs, we get:
9 ÷ 3 × 4 + 8 – 2
= 3 × 4 + 8 – 2
= 12 + 8 – 2
= 20 – 2
= 18
Hence,

Correct Answer: four

Solution : The correct answer is four.

A Wheatstone bridge consists of four arms, or resistors, where two arms have their ratio maintained at a fixed value, and the other two arms, or resistors, are left without any fixed value. This leaves the remaining arms balanced, with
