Question

What approximate value should come in place of the question mark (?) in the following equation? $23.94 	imes 17.91 + 64.89 	imes 59.98 = ?$

Accepted Answer

4330. This is an approximation question, so round each number to convenient values. $23.94 \approx 24$, $17.91 \approx 18$, $64.89 \approx 65$, and $59.98 \approx 60$; then $24	imes 18=432$ and $65	imes 60=3900$, giving about $4332$. The closest option is 4330.
