\\( \frac { ( 95 \times 15 \\% ) + ( 85 \times 15 \\% ) + ( 87 \times 15 \\% ) + ( 77 \times 15 \\% ) + ( 87 \times 20 \\% ) + ( 89 \times 20 \\% ) } { 100 \\% } \\)

Explanation:

Step1: Calculate each term

• Calculate \(95\times15\%\): \(95\times0.15 = 14.25\)
• Calculate \(85\times15\%\): \(85\times0.15=12.75\)
• Calculate \(87\times15\%\): \(87\times0.15 = 13.05\)
• Calculate \(77\times15\%\): \(77\times0.15=11.55\)
• Calculate \(87\times20\%\): \(87\times0.2 = 17.4\)
• Calculate \(89\times20\%\): \(89\times0.2=17.8\)
