A) 1500
B) 2000
C) 1000
D) 1200
E) None of these
Correct Answer: C
$ \Rightarrow $ $ ?=15.80\times 31+20.18\times 26 $
$ \Rightarrow $ $ ?=467.48+524.68=992.16\approx 1000 $ Alternate Method 31% of 1508 + 26% of 2018 $ \approx $ 30% of 1500 + 25% of 2000 $ =\frac{30}{100}\times 1500+\frac{25}{100}\times 2000 $ $ =30\times 15+25\times 20 $ $ =450+500=950\approx 1000 $
