Answer:
☆ Ratio will be 2:1 ☆
Step-by-step explanation:
Given:
- Average age of Lawyers and Doctors together is 40
- Doctor's average age is 35
- Lawyer's average age is 50
To Find:
- Ratio of number of Doctors to the Lawyers
Solution: Let the number of doctors be x and Lawyers be y
A/q
† Their average age is 40 †
Total age = 40(x + y ) = 40x + 40y..............(1)
★ Doctors average age= 35(x) = 35x
★ Lawyers average age = 50(y) = 50y
Total age of Doctors and Lawyers = Sum of Lawyers age + Sum of doctors age
∴ Total age = 50y + 35x .............(2)
→ From equation (1) and (2) ←
40x + 40y = 50y + 35x
40x – 35x = 50y – 40y
5x = 10y
x/y = 10/5
x/y = 2/1
x : y = 2 : 1
Hence, The ratio of Doctors age (x) to the Lawyers age (y) is 2:1
