The bar graph given below represents approximate length (in kilometres) of some National Highways in India. Study the bar

graph and answer the following questions:

Scale: 1 unit length = 200km

A. Which National Highway (N.H.) is the longest among the above?

B. Which National Highway is the shortest among the above?

C. What is the length of National Highway 9?

D. Length of which National Highway is about three times the National Highway10?

(A) N.H. 2

N.H.2 is 1500 km long which is the longest among all the other national highways.

(B) N.H.10

N.H.10 is 500 km long which is the shortest among all the other national highways.

(C) 900 km

From the graph , it can be observed that the length of the N.H.9 is 900 km.

(D) Length of N.H.2

From the graph , it is observed that length of NH2 = 1500 km

Length of NH3 = 1200 km

length of NH8 = 1400 km

length of NH9 = 900 km

length of NH10 = 500 km

So, length of NH10 = 1500 km = 3 500 km = 3 length of NH2.
