Question

A teacher takes $5$ children on a field trip to a geological museum. As a souvenir, the group receives a bag of stones. When the teacher divides the stones evenly among the children, each child receives exactly $24$. If $6$ children had been present, how many stones would each child have received?

• A. $15$
• B. $16$
• C. $18$
• D. $20$
• E. $21$

Answer 1

The correct option is D $20$

Total number of stones received $=5\times 24=120$
If there were $6$ children, then the number of stones each receives $=\frac{120}{6}=20$
