Admin from revisewise, Noida
Class : Class 1

The correct answer is B.

19-6+2=28+?-15

Let the missing number be x.

Then ,19 - 6 + 2 = 28 + x - 15 

=> x = 19 - 6 + 2 - 28 + 15 = (19 + 2 + 15) - (6 + 28) = 36 - 34 = 2

The correct answer is C.

The line segment joining a vertex of a triangle to the midpoint of its opposite side is called a median of the triangle. 
The perpendicular line segment from a vertex of a triangle to its opposite side is called an altitude of the triangle. 
A triangle has three altitudes and three medians.

Avinash Mishra from Central Hindu School, Gorakhpur
Subject :IMO    Class : Class 10

Ans 1: (Master Answer)

Admin from revisewise, Noida
Class : Class 1

The correct anser is D.

Circumference = 24πm, Width of track= 2 m 

As we know that circumference = 2πr
Therefore, 2πr = 24π

                   r = 12m

Now, Radius of outer circle = Radius of inner circle + Width of the track = 12 m + 2 m = 14 m
Again, Circumference of outer circle = 2πR = 2 X 3.14 X 14 = 88 m 

Hence, the quantity of wire required to surround the path completely is 88 m.
