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 +
