Question

problem questions :the salaries of a and b are in the ratio 2:3. what is the salary of a? statements: i)the salary of b is rs 8000 ii)the total salary of a and b is rs 15000

Answer 1

Answer:

either of the statement is sufficient to find the salary of a.

Step-by-step explanation:

Let the salary of a is x and that of b is y.

Then,

x:y = 2: 3

$\frac{x}{y}=\frac{2}{3}\\\\x=\frac{2}{3}y...(i)$

we have to find the salary of a. We'll check which statement is needed to find the same.

Statement i)

The salary of b is rs 8000. It means y = 8000

On substituting the value of y we can find x.

So, from this statement we can find salary of a.

Now, the statement (ii)

The total salary of a and b is rs 15000.

It means,

x + y = 15000

y = 15000-x

On substituting the value of y we can find x.

So, from this statement we can find salary of a.

Therefore, we can conclude that either of the statement is sufficient to find the salary of a.
