Question

solve this plz i reqire the answer

Answer 1

16.2 u = 16 × $\frac{x}{100}$ + 18 ×$\frac{100 -x} {100}$
 
16.2 u = $\frac{16 x}{100}$ + $\frac{1800 - x }{ 100}$
 
16.2 u = $\frac{16x + 1800 - 18 x}{100}$
 
16.2 × 100 - 1800 = (- 2 x  )
 
1620 - 1800  = ( - 2 x  )
 
- 180    =   - 2 x  (minus sign will get cancelled )
  
   180   =  2x
   
    $\frac{180}{2}$ = x 
 
     x = 90 
 
so ,
          x = 90 %
           100 - x = 100 - 90 = 10 %
