Solution

The correct option is D 7 units
Given: Both Raju and his mother are standing on the same side of the number line, taking 0 as the reference point.
Distance of Raju from the reference point = 3 units
Distance of Raju’s mother from the reference point = 10 units
So, the width of the road = Distance between Raju and his mother
= 10 - 3 = 7 units
