The first tank contains 285 liters of kerosene less than the second. 620 liters of kerosene were poured from the second tank. In which tank there is more kerosene and by how many liters?
Let the amount of kerosene, which was in the 1st tank, equal to C1, and in the 2nd – C2.
Since initially C2> C1 by 285 liters, then it turns out that C2 – 285 = C1.
C2 – C1 = 285.
After the amount of kerosene in the 2nd tank was reduced by 620 liters, the situation became as follows:
C21 = C2 – 620.
С21 – С1 = 285 – 620.
C1 – C21 = 335.
As a result, we got that the amount of kerosene increased in the 1st tank by 335 liters.
Answer: there is more kerosene in the first tank than in the second by 335 liters.
