Question : A takes 2 hours 30 minutes more than B to walk 40 km. If A doubles his speed, then he can make it in 1 hour less than B. What is the average time taken by A and B to walk a 40 km distance?
Option 1: 7 hours 15 minutes
Option 2: 5 hours 45 minutes
Option 3: 6 hours
Option 4: 5 hours 15 minutes
Correct Answer: 5 hours 45 minutes
Solution : Let the speed of A as $a$ km/hr and the speed of B as $b$ km/hr. $\text{Speed} = \frac{\text{Distance}}{\text{Time}}$ From the problem, A takes 2 hours 30 minutes more than B to walk 40 km. $⇒\frac{40}{a} = \frac{40}{b} + \frac{5}{2}$ If A
Question : Directions: In the following question, select the missing number from the given series. 10, 10, 20, 60, 240, ?
Option 1: 1150
Option 2: 1400
Option 3: 1200
Option 4: 1440
Correct Answer: 1200
Solution : Given: 10, 10, 20, 60, 240, ?
Multiply the previous term by consecutive natural numbers, to obtain the next term in the series – 10 × 1 = 10; 10 × 2 = 20; 20 × 3 = 60; 60 × 4 = 240; 240
Question : Directions: Select the combination of letters that when sequentially placed in the blanks of the given series will complete the series. AB_KPC_HKPEBH_PGBHK_
Option 1: CDGP
Option 2: HBKP
Option 3: CPHB
Option 4: HDGP
Correct Answer: HBKP
Solution : Given: AB_KPC_HKPEBH_PGBHK_
To fill the series we have to divide the series – AB_KP / C_HKP / EBH_P / GBHK_ Let's check each option – First option: CDGP; ABCKP / CDHKP / EBHGP / GBHKP (No repeated
Question : A prism has a regular hexagonal base with a side of 6 cm. If the total surface area of the prism is 216$\sqrt3$ cm2, then what is the height (in cm) of the prism?
Option 1: $3\sqrt3$
Option 2: $6\sqrt3$
Option 3: $6$
Option 4: $3$
Correct Answer: $3\sqrt3$
Solution : Given: Side, $a$ = 6 cm Let the height be $h$. Area of the base of the hexagonal prism $=6 \times \frac{\sqrt3}{4}a^2=6 \times \frac{\sqrt3}{4} \times 6^2 = 54\sqrt3$ Total curved surface area of prism = 2 × (Area of base) + 6 × (Side of

Question : The average of three numbers is 135. The largest number is 195 and the difference between the other two is 20. The smallest number is:
Option 1: 65
Option 2: 95
Option 3: 105
Option 4: 115
Correct Answer: 95
Solution : Given: The average of the three numbers is 135. The largest number is 195. According to the question, Let the smallest number be x then the other number will be (x + 20). The sum of number = 135 × 3 = 405 Now, 195

Question : If $\cos \theta+\sec \theta=\sqrt{3}$, then the value of $\cos ^3 \theta+\sec ^3 \theta$ is:
Option 1: $0$
Option 2: $\frac{1}{\sqrt{3}}$
Option 3: $\sqrt{3}$
Option 4: $2 \sqrt{3}$
Correct Answer: $0$
Solution : Given, $\cos \theta+\sec \theta=\sqrt{3}$ Cubing both sides, we get, $⇒\cos^3\theta + \sec^3\theta+3\cdot\cos\theta\cdot\sec\theta(\cos \theta+\sec \theta)=3\sqrt3$ ⇒ $\cos^3\theta+\sec^3\theta+3\times 1(\sqrt3)=3\sqrt3$ [$\because \cos\theta=\frac{1}{\sec\theta}$] ⇒ $\cos^3\theta+\sec^3\theta+3\sqrt3=3\sqrt3$ ⇒ $\cos^3\theta+\sec^3\theta=0$ Hence, the correct answer is $0$.
Question : Sanjay and Rohan can complete a work in 8 days and 12 days, respectively. Starting with Sanjay, they work on alternate days. In how many days will the work be completed?
Option 1: $8 \frac{1}{2}$
Option 2: $9 \frac{1}{2}$
Option 3: $9 \frac{2}{3}$
Option 4: $9 \frac{1}{3}$
Correct Answer: $9 \frac{1}{2}$
Solution : Time taken by Sanjay to complete the work = 8 days Part of work done by Sanjay in a day = $\frac{1}{8}$ Time taken by Rohan to complete the work = 12 days Part of work done by Rohan in a day = $\frac{1}{12}$
