Solution:

Let their salaries be Rs 600, Rs 900 and Rs 1,100.
Then, P’s increased salary = Rs

(600 + 15/100× 600 )

Q’s increased salary = Rs

( 900 +25/100×900)

= Rs 1,125
R’s increased salary = Rs

(100+20/100× 1,100 )

= Rs 1,320
∴ Ratio of their new salaries = 690 : 1,125 : 1,320 = 46 : 75 : 88
