A reasonable estimate for 1519/49 would be 31. This is because 1500 is divisible by 50, which is close to 49, and 31 is the closest whole number to 1519/49. Additionally, since 1519 is only slightly larger than 1500, rounding up to 32 would likely result in an overestimate. Therefore, 31 is a reasonable estimate for 1519/49.
