Answer 2

Given: Two third or three fourth of a number is 34.

To find: The 20% of that number.

Solution:

Let the number be equal to x. Now, according to the question, the following equation can be formed.

$\frac{2}{3}x + \frac{3}{4}x = 34$

The word 'or' in the question indicates that the two given fractions must be added. Now, the x terms are added and the value of x is found by cross multiplying the numbers.

$\frac{17}{12} x = 34$

$x = 24$

Thus, 20% of the number which is 24 can be calculated as follows.

$\frac{20}{100} * 24 = 4.8$

Therefore, the 20% of that number is 4.8.
