let monthly salary be 4x ,7x
it is increased by 2500 rupees
then the salaries are 4x+2500,7x+2500
given ratio of new salaries is 3/5
then,
4x+2500/7x+2500=3/5
cross multiplication
(4x+2500)5=(7x+2500)3
20x+12500=21x+7500
21x-20x=12500-7500
x=5000
4x=4×5000=20000 and
7x=7×5000=35000
it is increased by 2500 rupees
then the salaries are 4x+2500,7x+2500

4x+2500/7x+2500=3/5
cross multiplication
(4x+2500)5=(7x+2500)3
20x+12500=21x+7500
