Question

there are 3 numbers if first no is 4 times of 2nd number and 3 times the 3 rd number and average of the number is 95 find the 3 rd no

Answer 1

Answer:

60

Step-by-step explanation:

Let the 3 numbers be x,y,z

According to the question,

x = 4y   and  x = 3z

y = x/4  and  z = x/3

Average of 3 numbers = 95

{x + y + z} / 3 = 95

{x + x/4 + x/3} = 95 x 3

{12x + 3x + 4x} / 12 = 285

19x / 12 = 285

x = 285 x 12 / 19

  = 3420 / 19

  = 180

The third number is

z = x/3

  = 180/3

  = 60
