Question 50

Dr. Bappa has five gold rings, each having a different weight. Ring R1 is weighing twice as much as Ring R2. Ring R2 is weighing four and half times as much as Ring R3. Ring R3 is weighing half as much as Ring R4. Ring R4 is weighing half as much as Ring R5. Ring R5 is weighing less than Ring R1 but more than Ring R3. Which of the following represents the descending order of weights of the rings?

Solution

Above statements can be written as follows

$$R_1 = 2\times R_2$$

$$R_2 = 4.5\times R_3$$

$$R_3 = 0.5\times R_4$$

From above 3 we can conclude $$\ R_1>R_2>R_4>R_3$$. It is given that $$R_1>R_5>R_3$$
