As far as I can tell, the first would be B. If 292,000 is the third of all doctors, then assign the total of doctors (men and women) the value of d. That would be 786,000. In order to find the number of women doctors, you would have to divide by three, so the answer would be B: 292,000=d/3.
The second would be c. In the first ratio, 5:25, 5 is multiplied by 5 to get 25. Do the same with 7 and you get 35.

1. the choice is D.
lady doctors=1/3 total doctors=292,000
therefore total=292000*3
2.5.:25=7:x
so 5x=7*25. x=7*25/5=35 choice C

First would be B, second would be C.
Although I think you may have written the first one wrong. I am assuming d=the total number of doctors in 2020?
