Question : The speeds of a boat along the current and against the current are 10 km/hr and 8 km/hr, respectively. What is the speed (in km/hr) of the current?
Option 1: 1
Option 2: 2
Option 3: 3
Option 4: 9
Correct Answer: 1
Solution : Let the speed of the boat be $x$ km/hr. The speed of the current is $y$ km/hr. Speed of boat along the current = Speed of boat + Speed of current $x+y$ = 10 km/hr ----(1) Speed of boat against the current = Speed of
Question : A can do a piece of work in 8 days which B can destroy in 3 days. A has worked for 6 days, during the last 2 days of which B has been destroying; how many days must A work alone to complete the remaining work?
Option 1: $7\ \text{days}$
Option 2: $7\frac{1}{3}\ \text{days}$
Option 3: $7\frac{2}{3}\ \text{days}$
Option 4: $8\ \text{days}$
Correct Answer: $7\frac{1}{3}\ \text{days}$
Solution : Time taken by A alone to do the work = 8 days Part of work done by A alone in a day = $\frac{1}{8}$ Time taken by B alone to destroy the work = 3 days Part of work destroyed by B alone in
Question : What will be the LCM of 54 and 48?
Option 1: 412
Option 2: 456
Option 3: 423
Option 4: 432
Correct Answer: 432
Solution : Factors of 48 = 2 × 2 × 2 × 2 × 3 Factors of 54 = 2 × 3 × 3 × 3 So, the LCM of 54 and 48 = 2 × 2 × 2 × 2 × 3 × 3 × 3
Question : The ratio of the sides of a triangle is 11 : 11 : 4. If the area of the triangle is $2\sqrt{117}$ cm, then what is the length of the equal sides?
Option 1: 3 cm
Option 2: 13 cm
Option 3: 11 cm
Option 4: 9 cm
Correct Answer: 11 cm
Solution : Given: The ratio of the sides of a triangle is 11 : 11 : 4. The area of the triangle is $2\sqrt{117}$ cm2. A perpendicular bisector in an isosceles triangle bisects the base and acts as the height of the triangle. Let
Question : Punit goes from his home to his relative's place at a speed of 45 km/h. While returning from the relative's place, due to traffic, it takes him an hour longer as he can only drive at the speed of 40 km/h. Find the distance (in km) of his relative's place from his home.
Option 1: 400
Option 2: 720
Option 3: 180
Option 4: 360
Correct Answer: 360
Solution : Given, Speed while going = 45 km/h Speed while returning = 40 km/h Time is taken while returning - Time taken while going = 1 hour We know, Distance = Speed $\times$ Time Let's assume the distance between Punit's home and his relative's place to
Question : 2 cubes each of volumes 125 cm3 are joined end to end. The surface area of the resulting cuboid is:
Option 1: 325 cm2
Option 2: 350 cm2
Option 3: 125 cm2
Option 4: 250 cm2
Correct Answer: 250 cm2
Solution : Let the side of the cube be a. Volume of each cube = 125 cm3 ⇒ a3 = 125 $\therefore$ a = 5 cm So, the edge of each cube = 5 cm For new cuboid formed length(l) = 5 +
Question : Directions: In a certain code language, BECOME is coded as HPRFHE. What is the code for ACTIVE in that code language?
Option 1: HYLVFD
Option 2: HYLWDD
Option 3: HYLWFD
Option 4: HYLWFC
Correct Answer: HYLWFD
Solution : Given: BECOME is written as HPRFHE.
Add 3 to the place value of the letters of BECOME and then reverse the order of the letters as shown below –
Thus, BECOME is written as HPRFHE. Similarly, follow the same pattern for ACTIVE –
So. ACTIVE
Question : Directions: In a certain code language, GROW is written as RGWO, and PINK is written as IPKN. How will HALD be written in that code language?
Option 1: DLAH
Option 2: AHDL
Option 3: HADL
Option 4: AHLD
Correct Answer: AHDL
Solution : Given: GROW is written as RGWO, and PINK is written as IPKN.
Interchange the position of the first two alphabets followed by interchanging the position of the last two alphabets to obtain the required code. GROW→GR/OW→RGWO Thus, GROW is written as RGWO. PINK→PI/NK→IPKN Thus, PINK
