Let the ratio be 5x : 4x
Total number of people in group = 72
We need to calculate the number of lawyers in the group & it is also given that the ratio of doctor to lawyers is 5:4
Sun of Ratios = Total number of people
Substitute the value we get
:\implies:⟹ 5x + 4x = 72
:\implies:⟹ 9x = 72
:\implies:⟹ x = 72/9
:\implies:⟹ x = 8
Now, putting the value of x = 8
4x = 4×8 = 32
Hence, the number of lawyers in the group is 32 .
