Question

a no.is divided into three parts in the ratio of 1:2:3 . if the third part is 39 wat r the others? find the no.

Answer 1

let the 3 parts be x, 2x and 3x.
the required no. is equal to 6x.
so, 3x = 39.
so, x=13
the no.=13 X 6 = 78.
78 is the required no.

Answer 2

Answer:

Given that the ratio of three parts of a number is 1 : 2 : 3

Therefore the number can be calculated as: 1x + 2x + 3x = 6x

According to the question, the third part of the number is equal to 39.

→ 3x = 39

→ x = 39/3

→ x = 13

Therefore the other two numbers are: x, 2x which is 13, 26.

Hence the number is given as: 13 + 26 + 39 = 78

Therefore 78 is the required number.
