A certain amount is divided into 2 parts in the ratio of 6: 5. If the first part is Rs.282, then find the total amount (in Rs.).
517
517 is correct.
The first part corresponds to 6 ratio units, so one unit is \(\dfrac{282}{6}=47\).
The whole amount corresponds to \(6+5=11\) units.
Total amount: \(11\times47=517\), that is, ₹517.
