Question

1.Divide 180 into three parts so that, the second is thrice of first and the third is double of
second.​

Answer 1

Correct option is

A

490,392,280

We have, 4× first part =5× second part

=7× third part =x(say)

According to question,

4x+5x+7x=1162

⇒14035x+28x+20x=1162

⇒83x=1162×140⇒x=831162×140=1960

∴ First part =41960=490

Second part =51960=392

Third part =71960=280.
