In formocresol, ratio of formalin to cresol
1) 3:2
2) 2:3
3) 1:2
4) 2:1

📝 Explanation:

The ratio of formalin (formaldehyde) to cresol in the original Buckley's formocresol formula is approximately 1:2.

Specifically, the original or "full-strength" Buckley's formulation contains:

19% formaldehyde
35% cresol (or tricresol)
15% glycerin and 31% water.

This means the amount of cresol is nearly double that of formalin, making the ratio closer to 1:2.
