Question

A:B=4:5 B:C =5:6 A+B+C=69 then the values of A,B&C​

Answer 1

Answer:

A-18.4

B-23

C-27.6

Step-by-step explanation:

let A -4x,B-5x,C-6x

A.T.Q.

A+B+C=69

4x+5x+6x=69

15x=69

x=69/15

x=4.6

So,A=4x=4*4.6=18.4

B=5x=5*4.6=23

C=6x=6*4.6=27.6

Answer 2

Answer:

A=4B÷5; C=6B÷5

A+B+C=69

(4B÷5)+B+(6B÷5)=69

(4B+5B+6B)÷5 =69

15B=69×5

B=23

THEN A=92÷5

C=138÷5
