Question

divide 1800 among A B C in the ratio 3:4:5​

Answer 1

Let, A has = 3x

B has = 4x

C has = 5x

So, 3x + 4x + 5x = 1800

12x = 1800

X = 1800/ 12 = 900/6

X= 300/2= 150

So a has = 450

B has = 600

C has = 750

Answer 2

Answer:

let the common ratio be x

let A's share be 3x

let B's share be 4x

let C's share be 5x

B.T.P

5x+3x+4x=1800

or,12x=1800

or,x=1800/12=150

A=3x=450

B=4x=600

C=5x=750
