Question : Three tankers contain 403 litres, 434 litres and 465 litres of diesel respectively. Then the maximum capacity of a container that can measure the diesel of the three containers an exact number of times is:
Option 1: 31 litres
Option 2: 62 litres
Option 3: 41 litres
Option 4: 84 litres
Correct Answer: 31 litres
Solution : To determine the maximum capacity, we need to find the HCF of 403, 434 and 465. The prime factors of 403, 434 and 465 are: ⇒ 403 = 13 × 31 ⇒ 434 = 2 × 7 × 31 ⇒ 465 = 3 ×
Question : Which of the following has the highest penetrating power?

Option 2: Beta ray
Option 3: Gamma ray
Option 4: Delta ray
Correct Answer: Gamma ray
Solution : The correct answer is Gamma ray.
Radioactive nuclei emit three types of radiation: alpha, beta, and gamma rays. Alpha rays have the highest ionising power but the least penetrating power. Gamma rays are photons emitted by radioactive nuclei and have the lowest ionising power,
Question : Proportional taxes would help to reduce the autonomous expenditure multiplier because ________.
Option 1: taxes increase the MPC
Option 2: MPC does not have any role in it
Option 3: taxes and MPC become equal
Option 4: taxes reduce the MPC

Question : Directions: Select the option that is related to the fourth term in the same way as the first term is related to the second term and the fifth term is related to the sixth term. 7 : 40 :: ? : 667 :: 39 : 1512
Option 1: 34
Option 2: 25
Option 3: 47
Option 4: 26
Correct Answer: 26
Solution : Given: 7: 40:: ?: 667:: 39: 1512
Subtract 9 from the square of the first term to get the second number – Like in, 7 : 40→72 – 9 = 40 And in, 39 : 1512→392 – 9 = 1512 Similarly, follow the
Question : If ${\left(x-\frac{1}{x}\right)=\sqrt{6}}$ and $x > 1$, what is the value of ${\left(x^8-\frac{1}{x^8}\right)}$?
Option 1: $1024 \sqrt{15}$
Option 2: $992 \sqrt{15}$
Option 3: $998 \sqrt{15}$
Option 4: $1012 \sqrt{15}$
Correct Answer: $992 \sqrt{15}$
Solution : $(x-\frac{1}{x})=\sqrt{6}$ Squaring both sides, ⇒ $(x^{2} +\frac{1}{x^2}-2)=6$ ⇒ $(x^{2} +\frac{1}{x^2})=8$ Squaring both sides, ⇒ $(x^{4}+\frac{1}{x^4}+2)=64$ ⇒ $(x^{4}+\frac{1}{x^4}) = 62$ Squaring both sides, ⇒ $(x^{8}+\frac{1}{x^8}+2)=3844$ ⇒ $(x^{8}+\frac{1}{x^8})=3842$ ⇒ $(x^{8}+\frac{1}{x^8})^2=3842^2$ ⇒ $(x^{8}-\frac{1}{x^8})^2=(x^{8}+\frac{1}{x^8})^2 - 4$ ⇒ $(x^{8}-\frac{1}{x^8})^2=3842^2 - 2^2$ ⇒ $(x^{8}-\frac{1}{x^8})^2=(3842 +2)(3842-2)$ ⇒ $(x^{8}-\frac{1}{x^8})^2=3844 \times 3840$ ⇒
