What approximate value will come in place of question mark (?) in the given questions? (You are not expected to calculate the exact value)
Solution
Expression : 71.98 % of 1200 + 35.06 % of 270 = ? % of 600
=> $$(\frac{72}{100} \times 1200) + (\frac{35}{100} \times 270) = (\frac{x}{100} \times 600)$$
=> 864 + 94.5 = 6x
=> $$x = \frac{958.5}{6} \approx \frac{960}{6}$$
=> x = 160
