Two persons A and B get the same salary. Their Basic pay are different. The allowances are 65% and 80% of the basic pay respectively. What is the ratio of the basic pay? Correct Answer 12 : 11

Let the basic salaries of A and B be x and y respectively.
Now, salary of A = salary of B

x + 65 % of x = y + 80 % of y

x + 65/ 100 × x = y + 80/ 100 × y

x + 65x/ 100 = y + 80y/ 100

x/ y = 180/ 165

x: y = 12: 11

The ratio of their basic pay is 12: 11

Hence, “12: 11” is the correct answer.
