Question

a number is divided into three parts in the ratio 1:2:3 if the third part is 39 what are the others find the number also

Answer 1

Let the number be X

Then X/7 be the one seventh part of it.

And third part of the number i.e. 3*(X/7) is 39 (as given in question)

So,

=> 3*(X/7)= 39

=> X/7=> 13

=> X= 91

So other two parts are (X/7) and 2*(X/7)

=> X/7= 13

And

=> 2*(X/7)= 26

Answer 2

Heya !!


Let parts are X , 2X and 3X.


Given that : Third part = 39

3X = 39


X = 13.


First part = X = 13.

Second part = 2X = 2 × 13 = 26.

and,

Third part = 3X = 3 × 13 = 39.



Number = First part + Second part + Third part = 13 + 26 + 39 = 78.
