Question
What approximate value will come in place of the
question mark (?) in the following question? (Note: You are not expected to calculate the exact value.) 4.01 X ? ²- 11.93 X (54.01 - 8.99) = 44.01 X 10.98Solution
ATQ,
4.01 X ? ²- 11.93 X (54.01 - 8.99) = 44.01 X 10.98
4 X ? ²- 12 X (54 - 9) ~ 44 X 11
4 X ? ²- 12 X 45 ~ 484
4 X ? ²- 540 ~ 484
4 X ? ²~ 1024
? ²~ 256
? ~ ± 16
