Question

please find the answer by solving​

Answer 1

Answer:

2:1

Step-by-step explanation:

LET THE NUMBER OF TEACHERS BE x

AND PROFESSORS = y

GIVEN:-

THE AVERAGE AGE OF TEACHERS AND PROFESSORS IS 40 YEARS.

HENCE,

SUM OF THE AGE OF TEACHERS AND PROFESSORS = 40(x +y)

AGAIN,

THE AVERAGE AGE OF THE TEACHERS IS 35 YEARS.

HENCE,

SUM OF THE AGE OF THE TEACHERS = 35×x = 35x

AGAIN,

THE AVERAGE AGE OF THE PROFESSORS IS 50 YEARS.

HENCE,

SUM OF THE AGE OF THE PROFESSORS = 50×y = 50y

A/Q

35x+50y = 40(x+y)

=> 35x+50y = 40x+40y

=> 40x-35x = 50y-40y

=> 5x = 10y

=> x/y = 10/5

x:y = 2:1

THEREFORE, THE RATIO OF THE

NUMBER OF THE TEACHERS TO THE PROFESSORS = x:y = 2:1 Ans.
