Question

A disaster relief team consists of engineers and doctors in the ratio of 2 : 5,If there are 65 doctors, find the number of engineers.

Answer 1

Engineers : Doctors = 2 : 5 (Given)

Define x:

Let x be the constant ratio

Engineers : Doctors = 2x : 5x

Solve x:

There are 65 doctors

5x = 65

x = 13

Find the number of engineers:

Engineers = 2x = 2(13) = 26

Answer: There are 26 engineers

Answer 2

Given Ratio -

Engineers : Doctors

2 : 5

let the ratio be 2x : 5x

Given Doctors are 65 .

Finding the value of "x" -

5x = 65

x = 65 ÷ 5

x = 13.

Finding the number of engineers -

Number of engineers 2x = 2(13) = 26 .

$\bold{Number \: of \: engineers \: = \: 26}$
