1.  $1.60 × 4 + $0.80 = $7.20  
He pays $7.20 for 5 chicken wings.

 $110 ÷ $7.20 = 15 R $2     

 15 × 5 + 1 = 76

He can buy 76 chicken wings

2.  0.75 ® 540    (men)

     0.25 ® 180    (women)

      540 + 180 = 720 (adults)

      60% ® 720

     100% ® 1200          

     1200 – 720 = 480 (children)

      480 – 276 = 204 (boys)

       (204 / 1200) x 100% = 17%

Ans: 17%


OR 

      9u ® 540

      1u ---   60

    12 u ----  60 x 12 = 720 

   Adult ----- 720

  Children -----  60 x 8 = 480

      480 – 276 = 204 (boys)

(204 / 1200 ) x 100%  = 17%
