A's salary is 80% of B’s salary. Find what percentage of A’s salary is B’s salary?

Answer 1

Answer:

125%

Step-by-step explanation:

Define x:

Let B's salary be x

A's salary is 80% of B's salary

⇒ A's salary = 0.8x

Percentage of A's salary is B's salary:

Percentage = (x ÷ 0.8x)  x 100 = 125%

Answer: B's salary is 125% of A's salary

Answer 2

Let the Salary of the Person B be Rs. Y.

Therefore, A's per as the question, Salary of the Person A = 80/100 × Y

= Rs. 0.8Y

Let Salary of A be Rs. X.

∴ X = Rs. 0.8Y

∴ Y = Rs. X/0.8

Salary of the B = Rs. Y

= X/0.8

= 5/4 × A

Let us change it into Percentage by multiplying it with 100.

∴ Salary of B = 5/4 × 100 A

∴ Salary of B = 125 % of A.
