Question

The sum of three numbers is 280. The first and second numbers are in the ratio 1:3 and the second and third are in the ratio 2:3, then the second number is?

Answer 1

Answer:

x=30

y=90

z=60

first calculate the value of x and z in the form equivalent to y

and then put in the given equation

Answer 2

$A+B+C =280$

$A:B = 1:3$

$B:C =2:3$

$A:B:C = 2 : 3 : 6$

$2x+3x+6x = 280$

$10x = 280$

$x = 28$

$B = 3x = 3×28=84$
