the average price of three items is Rs.1800 If their price is in the ratio 1 : 3 : 5 , then the price of the costliest item is?
Answer & explanation
Correct answer: option 4
ratio is 1 : 3 : 5
1R +3R + 5R = 9R
9R = 1800
1R = 200
costliest item = 5R = 5 × 200 =1000
so price of costliest item is Rs.1000
