If 3x/4 = 1, then x is greater than 3/4 approximately by what percent?

Question: If 3x/4 = 1, then x is greater than 3/4 approximately by what percent?

Solution:
Given that,
3x/4 = 1
⇒ 3x = 4
∴ x = 4/3

∴ Difference = x - (3/4) = (4/3) - (3/4)
= (16 - 9)/12
= 7/12

∴ Percentage increase = (Difference/Original)​ × 100%
= {(7/12)/(3/4)}​ × 100%
= (7/9) ​ × 100%
= 77.78%
= 78%

∴ Rounded to the nearest whole number 78%. (Correct answer গ)
