Question

$A^{\prime }{B}^{\prime }$ & ${}^{\prime }{C}^{\prime }$ are going to buy books that cost $Rs540$ if A pays $Rs40$ more than B and B pays twice as much as C, how much does C pay?

• A. $Rs100$
• B. $Rs140$
• C. $Rs160$
• D. $Rs200$

Answer 1

The correct option is A $Rs100$

Let the cost paid by $C$ be $x$

The cost paid by $B$ is $2x$

The cost paid by $A$ is $2x+40$

The total cost is $x+2x+2x+40=5405x+40=5405x=500x=100$
