Question
√48.75 + √144.56 + 68.34% of (305.48 + 18.45% of 91.33)
= ? 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.)Solution
ATQ;
√48.75 + √144.56 + 68.34% of (305.48 + 18.45% of 91.33) = ?
√49 + √144 + 68% of (306 + 18% of 91) ~ ?
7 + 12 + 68% of (306 + 16) ~ ?
? ~ 19 + 68% of 322
? ~ 19 + 219
? ~ 238
