Question 39
The bar graph given below represents approximate length (in km ) of some national highways in India.

Study the bar graph and answer the following questions:
(a) Which National Highway (NH) 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 Highway 10?

(a) National Highway 2 is the longest among the above-shown highways. It is 1500 km long.
(b) National Highway 10 is the shortest among the above-shown highways. It is 500 km long
(c) The length of National highway 9 is 900
(d) Length of NH 10 = 500 km
Length fo NH 9 = 900 km
Length of NH 8 = 1400 km
Length of NH 3 = 1200 km
and length of NH 2 = 1500 km
clearly, the length of NH 2 is three times the length fo NH 10 ( $3\times 500=1500$ ).
