Question

divide 1400 into three parts such that the first part is 2/3 of second part and the ratio between the second and third part is 4:5 find each part (with full explanation)​

Answer 1

Let the common multiple be x

given ratio: of part second and third 4:5

:. second part=4x

third part=5x

given:first part=2/3×4x=8x/3

for 2nd condition:

1 +2+3 part= 1400

8x/3+12x+5x=4200

35x=4200

soo therefore x=120

1 part=8x/3=320

2 part=480

3 part 5x=600

Different Parts are all above mentioned

(320; 480; 600)
