The average price of four items is Rs 6,300. If their prices are in the ratio 1 : 2 : 4 : 5, what is the price of the costliest item?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → Rs 10,500
The average gives the total price (average \(\times\) number of items); the ratio then splits that total.
Total price \(=4\times6300=\) Rs 25,200
Parts \(=1+2+4+5=12\), so 1 part \(=\) Rs 2100
Costliest item \(=5\times2100=\) Rs 10,500
The costliest item costs Rs 10,500.
