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.) ? = {(92.77 β 45.33) + (28.85 β 14.91)} Γ 5.02Solution
ATQ,
? = {(92.77 β 45.33) + (28.85 β 14.91)} Γ 5.02
? ~ {(93 β 45) + (29 β 15)} Γ 5
? ~ (48 + 14) Γ 5
? ~ 62 Γ 5
? ~ 310
