Question : How much time will it take for an amount of Rs. 450 to yield Rs. 47.25 as interest at 3.5% per annum of simple interest?
Option 1: 1 year
Option 2: 2 years
Option 3: 3 years
Option 4: 4 years
Correct Answer: 3 years
Solution : Given: Principal = Rs. 450 Simple interest = Rs. 47.25 Rate = 3.5% We know that, Simple interest = $\frac{\text{Principal × Rate × Time}}{100}$ ⇒ $47.25 = \frac{\text{450 × 3.5 × Time}}{100}$ ⇒ Time = $\frac{47.25\times100}{450\times3.5}$ ⇒ Time = $\frac{4725}{1575}=3$ years Hence, the correct
Question : The radius of a right circular cylinder is thrice of its height. If the height of the cylinder is 3.5 cm, what is the volume of the cylinder?
Option 1: 1124.25 cm3
Option 2: 1324.75 cm3
Option 3: 1468.25 cm3
Option 4: 1212.75 cm3
Correct Answer: 1212.75 cm3
Solution : The height of the cylinder, $h$ = 3.5 cm So, radius, $r$ = 3.5 × 3 = 10.5 cm Now, the volume of the cylinder = $\pi r^2 h=\frac{22}{7}×(10.5)^2×3.5=1212.75\ \text{cm}^3$ Hence, the correct answer is 1212.75 cm3.
Question : Directions: Select the option figure in which the given figure (X) is embedded as its part (Rotation is NOT allowed).
Option 1:
Option 2:
Option 3:
Option 4:
Correct Answer:
Solution : Since the rotation is restricted. So, the embedded figure will have the same orientation as the main figure. By comparison of all the option figures, the given question figure is embedded only in the third option figure.

Question : Directions: Select the option that is related to the fifth term in the same way as the second term is related to the first term and the fourth term is related to the third term. AR37 : DW44 :: PQ43 : SV50 :: GF31 : ?
Option 1: JJ38
Option 2: KK38
Option 3: JK38
Option 4: KM38
Correct Answer: JK38
Solution : Given: AR37 : DW44 :: PQ43 : SV50 :: GF31 :?
Like, AR37 : DW44→A(1) + 3 = D; R(18) + 5 = W; 37 + 7 = 44 And, PQ43 : SV50→P(16) + 3 = S; Q(17) + 5 = V; 43 + 7

Question : In a room, there are 36 women and 20 men. What is the ratio of men to the total number of people in that room?
Option 1: 14 : 11
Option 2: 5 : 14
Option 3: 5 : 11
Option 4: 5 : 13
Correct Answer: 5 : 14
Solution : The total number of people in the room is the sum of the number of women and men = 36 + 20 = 56 $\therefore$ The ratio of men to the total number of people in the room = $\frac{20}{56}$ = $\frac{5}{14}$ Hence,
Question : The difference between compound interest (compounding annually) and simple interest on a sum at the rate of 30% per annum for 2 years is INR 3,600. What is the sum?
Option 1: INR 75,000
Option 2: INR 40,000
Option 3: INR 50,000
Option 4: INR 60,000
Correct Answer: INR 40,000
Solution : Difference between compound interest (compounding annually) and simple interest = INR 3600 Rate, $R$ = 30% Term = 2 years Let $P$ be the principal sum. Difference between compound interest (compounding annually) and simple interest for 2 years $=P×(\frac{R}{100})^2$ $⇒ 3600 = P×(\frac{30}{100})^2$ $⇒
