Question

Sa;aries of a and b are in the ratio 2:3 if salary of a is increased by 4000 and salary of b is increased by 1500 then the new ratio becomes 4:3 find b new salary

Answer 1

Answer:

4500

Step-by-step explanation:

a:b :: 2:3

ie 3a = 2b    _     _    _    _ (1)

given a+4000:b+1500 :: 4:3

ie 3(a+4000) = 4(b+1500)

3a + 12000 = 4b + 6000

2b + 12000 = 4b + 6000       _    _ value of 3a from (1)

2b = 6000

b = 3000

therefore the new salary of b = 3000 + 1500 = 4500
