Distance between 10 to 40 = 30 units

=> 2/5 of this distance = (2/5)*30 = 12 units

=> Required Point = 10+12 = 22

=> Answer: E

Distance between two number on number line = highest value - lowest value.
=> Distance = 40-10
=> Distance = 30

The 2/5th proportion of 30 =
=> 2/5*30
=> 12

12 is the distance from 10 on number line.
The point on number line = 10+12 = 22

=> ANSWER is E

Solution



• On the number line, distance between 10 and 40 \(= |40 – 10| = 30\)
• Now, \(\frac{2}{5}\)th of the distance between 10 and 40 \(= \frac{2}{5} * 30 = 2*6 = 12\)
Thus, the correct answer is Option C.

First, let's find out the distance between 40 and 10

40-10 = 30

Now, we need to find 2/5th of this distance
ie, 2/5 * 30 = 12

Now we got the distance.

In order to find the value on the number line, we have to add this value to 10

ie, 10+12 = 22

Answer = E
