Question 3 (i)
Population of Rajasthan = 570 lakhs, population of UP= 1660 lakhs.
Area of Rajasthan = 3 lakh $k m^{2}$ and area of UP = 2 lakh $k m^{2}$
How many people are there in per $k m^{2}$ in both these states?

Population of Rajasthan is $570 l a k h$ and population of UP is $1660 l a k h$ .

Area of Rajasthan is $3 l a k h$ / $k m^{2}$ and area of UP is $2 l a k h$ / $k m^{2}$

$(i)$ How many people are there per $k m^{2}$ in both these states?

$(i i)$ Which State is less populated?

A television tower of height 140m can broadcast its signal upto a maximum area of (Radius of earth =6.4×106m)

The correct option is B 5.6×103km2For TV signals, area covered =2πRh=2×π×6.4×106×140 =5.6×109m2=5.6×103km2

A television tower of height $140 m$ can broadcast its signal upto a maximum area of (Radius of earth $= 6.4 \times 10^{6} m$ )

The correct option is B $5.6 \times 10^{3} {k m}^{2}$
For TV signals, area covered $= 2 π R h = 2 \times π \times 6.4 \times 10^{6} \times 140$
$= 5.6 \times 10^{9} m^{2} = 5.6 \times 10^{3} {k m}^{2}$
