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 ?

Options

A. `7:5`
B. `17:15`
C. `12:11`
D. `11:10`

Answer

C

Explanation

Let basic pay of A = Rs x
Let basic pay of B = Rs y
As per given condition
Total salary = x + 0.65 x = 1.65 x of A
Total salary of B = y + 0.80y = 1.8y
1.65 X = 1.8y
`(x)/(9y) = (1.8)/(1.65) = (180)/(165)= (12)/(11)`
So ratio of basic pay = 12:11
