Let total examines is X
65% examines has passed
Failed examines=100-65=35%
Number of Failures= 420
35% of X = 420
35/100* X=420
X=420*100/35
X=1200

Let the salaries of A & B= 9x & 4x
What is 15% of A Salary=?
15/100*9x=27/20x
Now, The salary of A
9x + 27/20 x=5175
(180x+27x) / 20=5175
207x/20=5175
207x=5175*20
207x=103500
x=103500/207
x=500
The salary of B is =4x
4x=4 (500)
B=2000
