Correct answer: B
Step-by-Step Solution
To solve this, we will represent the number as X and use the information given to find its value, then calculate the required percentage.
Translate the problem into an equation:
"Two-third of three-fourth of a number is 34"
(2 / 3) * (3 / 4) * X = 34
Simplify and solve for X:
Multiply the fractions: (2 * 3) / (3 * 4) = 6 / 12 = 1 / 2
So, (1 / 2) * X = 34
X = 34 * 2
X = 68
Find 20% of the number:
20% of 68 = (20 / 100) * 68
0.2 * 68 = 13.6
