The General Hospital is comprised of, 3/5 Pediatricians, 1/4 Surgeons, and the rest are GP doctors.
The General Hospital is comprised of, 3/5 Pediatricians, 1/4 Surgeons, and the rest are GP doctors. If 1/4 of the Surgeons are Heart Surgeons, and the hospital doubles the number of GP doctors, what proportion of the hospital are now Heart Surgeons?
Answer/Solution
1/24
Steps/Work
Ped = 3/5 = 12/20
Sur = 1/4 = 4/20
GP = 1 - (12/20 + 4/20) = 1 - 16/20 = 4/20
HSur = (1/4)(4/20) = 1/20
If GP doubled => (2)(4) = 8; then, total = 12 + 4 + 8 = 24,
and 1 is HSur => proportion = 1/24.
Answer: D
Sur = 1/4 = 4/20
GP = 1 - (12/20 + 4/20) = 1 - 16/20 = 4/20
HSur = (1/4)(4/20) = 1/20
If GP doubled => (2)(4) = 8; then, total = 12 + 4 + 8 = 24,
and 1 is HSur => proportion = 1/24.
Answer: D
