Solution

The correct option is B Only Statement - 2
Statement - 1:
Length of saree =5.5 m5.5×100=550 cm
Width of saree =1.25 m=1.25×100=125 cm
Shaded region shows zari border.
Area of zari along the length of saree
=2×2.5×550=2750 cm2
Area of zari along the width of saree
=120×5+120×25
=600+3000=3600 cm2
Hence, total area covered with zari
=2750+3600=6350 cm2
Statement - 2 : Distance of moon from earth =384000 km
Length of path is equal to the circumference of the circular path.
So, 2πr=2×3.14×384000 km=3,411,520 km
Hence, the length of path described by moon in one complete revolution is 2,411,,520 km.
