Question

$A$'s salary is same as $4$ times $B$'s salary. If together they earn Rs. $3,750$ a month, find the salary of each.

• A. $A$'s $=$ Rs. $3000;B$'s $=$ Rs. $750$
• B. $A$'s $=$ Rs. $2000;B$'s $=$ Rs. $800$
• C. $A$'s $=$ Rs. $2500;B$'s $=$ Rs. $900$
• D. $A$'s $=$ Rs. $4500;B$'s $=$ Rs. $1000$

Answer 1

The correct option is A $A$'s $=$ Rs. $3000;B$'s $=$ Rs. $750$

Let A's salary be $x$

So according to question B's salary will be $4x$

since, together they earn Rs. $3,750$

Therefore, $x+4x=3750$

$5x=3,750$

$x=\frac{3750}{5}$ [Dividing both the sides with $5$]

$x=750$

Therefore, A's salary will be $Rs.750$

and B's salary will be $4\times 750$ i.e. $3000$

Option $A$ is correct.
