Question : The curved surface area of a right circular cone of diameter $42 \ \text{cm}$ is $990 \ \text{cm}^2$. What is the slant height (in${\ \text{cm}})$ of the cone? [Use $\pi=\frac{22}{7}$]
Option 1: 10
Option 2: 15
Option 3: 24
Option 4: 12
Correct Answer: 15
Solution : Diameter = $42 ~cm$ Radius, $r$ = $21 ~cm$ Let $l$ be the slant height. Curved surface area of a right circular cone = $990 \ \text{cm}^2$ ⇒ $\pi r l = 990$ ⇒ $\frac{22}{7}×21×l = 990$ ⇒ $l$ = $\frac{990}{66} = 15 \ \text{cm}$

Question : Directions: In a certain code language, NIGHT is coded as 96270. OFTEN is coded as 87561, and PILOT is coded as 23745, What is the code for INF in that code language?
Option 1: 257
Option 2: 269
Option 3: 264
Option 4: 268
Correct Answer: 268
Solution : Given: 1. NIGHT ⇒ 96270 2. OFTEN ⇒ 87561 3. PILOT ⇒ 23745
By comparing all the above-coded words, we find that – In words 1, 2 and 3, T is a common letter and 7 is a common code. In words 1 and 3,
Question : Directions: A man climbing up a wall 24 m high. He climbed 16 m on one day but slipped back by 3.40 m in the evening. How far had the man reached on that day?
Option 1: 19.40 m
Option 2: 12.60 m
Option 3: 11.40 m
Option 4: 12.40 m
Correct Answer: 12.60 m
Solution : Given: Total height of wall = 24 m Height climbed by man = 16 m Height by which he slipped = 3.40 m
⇒ Total height climbed by man = (16 – 3.40) m = 12.60 m
So, he had reached 12.60 m far
Question : Directions: If PONDERS is coded as ONMCDQR, how will MAT be coded?
Option 1: LZS
Option 2: OLJ
