In a factory there are three types of Machines M1 , M2 and M3 which produces 25%, 35% and 40% of the total products respectively. M1, M2 and M3 produces 2% , 4% and 5% defective products, respectively. What is the percentage of non-defective products?

• Option 1)

89%

• Option 2)

87.07%

• Option 3)

96.1%

• Option 4)

86.1%

• Option 5)

97.1%

% of non defective products =  $\dpi{100} \left ( \frac{25\times 98}{100} \right )+\left ( \frac{35\times 96}{100} \right )+\left ( \frac{40\times 95}{100} \right )=96.1\, ^{0}/_{0}$
