Question

divide 64 in two parts so than one part is three times the other part

Answer 1

let one the parts be x
other part be 3x
as per question,
3x and x are two parts of 64
then,
3x + x = 64
4x = 64
therefore ,x = 64 /4 = 16

so , one part = x = 16
other part = 3x = 3*16 = 48
verification,
16+ 48 = 64
thus, 16 and 48 are two parts of 64.

Answer 2

Let one part be x.Then the other part is 3x.
A.T.Q.
x+3x=64
or,4x=64
or,x=64/4=16
Hence,one part is 16 and the other part is (3×16)=48.
