Question 553318
average of y and z= 27
so,
{{{(y+z)/2 = 27}}}
{{{y+z = 54}}} -----(1)
.
average of x,y and z is 32.
so, 
{{{(x+y+z)/3 = 32}}}
{{{x+y+z = 96}}} -----(2)
from equation one we have y+z = 54.
so, x+ 54 = 96.
x= 42.
so, 2x= 84.
average of x and 2x is : {{{(42+84)/2 = 126/2 = 63 }}}
so, 63 is the answer of this.
