In millions of barrels per day, the three top countries consume 32.2 million barrels of the world’s oil. The United States consumes 12 million more barrels a day than China. China consumes 3.2 million barrels a day than Japan. How many barrels of the world oil consumption did the United States, Japan, and China consume

Respuesta :

Answer: Consumption of,

Japan = 4.6 million barrel,

China = 7.8 million barrel,

The US = 19.8 million barrel.

Step-by-step explanation:

Let x be the quantity of oil per day consumed by Japan,

∵ China consumes 3.2 million barrels a day than Japan.

So, the consumption of China = ( x + 3.2) million Barrel,

Also, The United States consumes 12 million more barrels a day than China.

So, the consumption of the US = (x + 3.2 + 12) = (x + 15.2) million barrel,

Thus, the total consumption of these three countries

= x + x + 3.2 + x + 15.2

= (3x + 18.4) million barrel,

According to the question,

3x + 18.4 = 32.2

3x = 32.2 - 18.4

3x = 13.8

⇒ x = 4.6

Hence, Japan, China and the US consume 4.6 million barrel, 7.8 million barrel and 19.8 million barrel respectively.
