Question

The average age of doctors and lawyers together is 40. If the doctors average age is 35
and the lawyers average age is 50, find the ratio of the number of doctors to the number of
lawyers​

Answer 1

Answer:

the ratio of doctors and lawyers = 2:1

Step-by-step explanation:

let the no of doctors = m

let the no of lawyers = n

given average of doctors = 35

d1 +d2+d3+.......+dm / m=35

d1+d2+d3 +.....+dm= 35m

given average of lawyers= 50

L1+L2+L3+......+Ln/n=50

L1+L2+L3+....+Ln=50n

given average of doctors and lawyers = 40

d1+d2+....+dm+L1+L2+.....Ln/m+n= 40

d1+d2+...+dm+L1+L2+....+Ln=40(m+n)

35m+50n= 40m+40n

50n-40n=40 m - 35m

10n=5m

10/5=m/n

2/1=m/n

therefore the ratio of doctors and lawyers is 2:1
