Direction: What approximate value should come in place of question mark (?) in the following questions? |
A) 282
B) 275
C) 264
D) 289
E) 294
Correct Answer: A
Solution :
\[84\frac{1}{7}+92+\frac{1}{4}+105\frac{3}{7}=?\] or, \[?=(84+92+105)+\left( \frac{1}{7}+\frac{1}{4}+\frac{3}{7} \right)\] \[=281+\left( \frac{4+7+12}{28} \right)=281+\frac{23}{28}\approx 282\]You need to login to perform this action.
