Solution



Given:
    • The capacity of the river tanker R is 50 percent greater than the capacity of the sea-going tanker S

To find:
    • How many more gallons of oil are currently in tanker R than in tanker S

Analysing Statement 1
    • As per the information given in statement 1, tanker R is 90 percent full; tanker S is 40 percent full
      o This statement does not provide us any specific information about the exact amount of oil present in the tanks

Hence, statement 1 is not sufficient to answer

Analysing Statement 2
    • As per the information given in statement 2, tanker R can contain maximum 40,000 gallons of oil
      o This statement does not provide any information about the present level of oil in both the tanks

Hence, statement 2 is not sufficient to answer

Combining Both Statements
Combining both the statements, we can say
    • Capacity of R is 40000 gallons
    • Capacity of S = 40000/1.5 gallons

We know R is 90% full and S is 40% full

Therefore, we can find the individual quantities of oil in R and S respectively

Hence, the correct answer is option C.

Answer: C

(1) Tanker R is 90 percent full; tanker S is 40 percent full.
(2) When full, tanker R contains 40,000 gallons of oil.


Let R & S be the capacity of Tanker R & Tanker S.

Given R = 1.5*S

Asked, Difference in gallons of current Oil in Tanker R & S


Statement 1: Gives us information of current levels in % of capacity.

Amount of Oil in R = 90% of R & Amount of Oil in S = 40% of S

We do not know absolute values of capacity in gallons.

Hence Statement 1 alone is Not Sufficient.


Statement 2: Gives R = 40,000 gallons

No information about current levels of R & S.

Hence Statement 2 alone is Not Sufficient.


Combining both, we can find current levels & hence the difference.

Combining is Sufficient.

Answer C.



Thanks,
GyM
