​

Answer 1

Step-by-step explanation:

Your required answer is here...

Clearly, A and B save 20% and 30% of their respective salaries

Let the salaries of A and B be x and y respectively

Then,

= 20% of x/30% of y=4/3

⇒x/5×103/y=4/3

⇒x/y=2

⇒x=2y

∴x+y=2100

⇒2y+y=2100

⇒3y=2100

⇒y=700

A's salary=x=2y=Rs. (2×700)=Rs. 1400
