JEE Main Chemistry question

An organic compound has C and H percentage in the ratio 6 : 1 and C and O percentage in the ratio 3 : 4. The compound is:

Answer: (A)

Solution

Let %C = x. Then %H = x/6 and %O = (4/3)x. Summing: x + x/6 + 4x/3 = 100 ⟹ (15x/6) = 100 ⟹ x = 40. So %C = 40, %H = 6.67, %O = 53.33. Moles: C =
