Question

A point X on a line segment AB = 30 cm divides it in the ratio 1 : 2. What will be the measure of segment AX ?

• A. 15 cm
• B. 20 cm
• C. 10 cm
• D. 5 cm

Answer 1

The correct option is C 10 cm

Sum of terms of the ratio = 1 + 2 = 3
$\Rightarrow$ Value of 3 parts = 30 cm
$\Rightarrow$ Value of 1 part
$=\frac{30}{3}=10cm$
$\therefore$ Measure of segment AX = Value of 1 part = 10 cm
