Solution
The correct option is C 32
Rahul needs 5 sticks to make a "2” and 6 sticks to make a "6”.
There are four "2”s in 262226.
So, the number of sticks needed to make four "2”s = 4 × 5 = 20 sticks.
There are two "6”s in 262226.
So, the number of sticks needed to make two "6”s = 2 × 6 = 12 sticks. Total number of sticks needed = 20 + 12 = 32 sticks.
