Question

The steps of a number ladder have the numbers 2, 4, 6, 8 and 10 from bottom to top.
The number in the next step of the ladder is .

• A. 11
• B. 12
• C. 14

Answer 1

The correct option is B 12


We know that $2+2=4,4+2=6,6+2=8$ and $8+2=10.$

$\therefore$ The number in a higher step of the ladder is got by adding 2 to the one in the step just below it.

$\Rightarrow$ The number on the next step of the ladder is got by adding 2 to 10.
$10+2=12$


That is, 12 is the number on the topmost step of the ladder.
