Question

Raju bought $\mathrm{x}$ packet of pencils, each containing $10$ pencils. He distributed $6$ packets. Which expression shows the number of pencils left with him?

Answer 1

Formation of an Expression:

Packet bought by Raju $=\mathrm{x}$

Number of pencils in $1$ packet $=10$

Total number of pencils $=\mathrm{x}\times 10=10\mathrm{x}$

Number of packets distributed by Raju $=6$

i.e. number of pencils distributed by Raju $=6\times 10=60$

Therefore, the number of pencils left with Raju $=10\mathrm{x}-60$
