Question : Directions: If J means +, K means –, T means ×, and U means ÷, then, 18 T 3 U 27 J 2 = ?
Option 1: 6
Option 2: 2
Option 3: 4
Option 4: 3
Correct Answer: 4

Hence, the third option is correct.
Question : The length and breadth of a rectangular field are in the ratio of 4 : 3. If the perimeter of the field is 70 m, then what will be the breadth (in metres)?
Option 1: 12
Option 2: 15
Option 3: 18
Option 4: 24
Correct Answer: 15
Solution : Given: Ratio of length and breadth = 4 : 3 Perimeter = 70 m Let the length be $4x$ and breadth be $3x$. Perimeter of rectangle = 2 × (Length + Breadth) $⇒ 70=$ 2 × (Length + Breadth) $⇒2×(4x + 3x) = 70$ $⇒7x=

Question : The surface areas of the two spheres are in the ratio of 64 : 81. Find the ratio of their volumes, in the order given.
Option 1: 512 : 729
Option 2: 64 : 729
Option 3: 8 : 81
Option 4: 4 : 9
Correct Answer: 512 : 729
Solution : let $r_1$ and $r_2$ be the radius of the sphere. Given: $\frac{\text{surface area of 1st sphere}}{\text{surface area of 2nd sphere}} = \frac{64}{81}$ ⇒ $\frac{4\pi r_1^2}{4\pi r_2^2} = \frac{64}{81}$ ⇒ $\frac{r_1}{r_2}=\frac{8}{9}$ Now, $\frac{\text{The volume of 1st sphere}}{\text{The volume of 2nd sphere}} = \frac{\frac{4}{3}\pi r_1^3}{\frac{4}{3}\pi
Question : Directions: In the following question, some parts of the sentence have errors and some are correct. Find out which part of the sentence has an error. The number of that part is the answer. If a sentence is error-free, your answer is "No Error".
