Answer 1

hye

========================

The income of a man is increased in the ratio10:11 .

=> the increase in his income is rs600 per month, 

let total income be x

then new income is x +600

ratio of old to new income = 10:11

so lets form an equation

=>x :x +600 = 10:11

=>x/x +600 = 10/11

=>11*x = 10[x +600]

=>11x = 6000 +10x

=>11x - 10x = 6000

=>x = 6000

so his new income is rs 6000
