Question

There are $160$ toys in a shop. A pair of toys consists of $2$ toys. If $20$ pairs of toys get sold, how many pairs of toys are left in the shop?

• A. $60$ pairs
• B. $80$ pairs
• C. $40$ pairs
• D. $320$ pairs

Answer 1

The correct option is A $60$ pairs

Let’s assume that $“x”$ pairs of toys are left in the shop.
Total number of toys $=160$
Number of pairs $=160÷2$
Let’s use the area model.

$160÷2=80$
There were 80 pairs of toys.
Therefore, there were $80$ pairs of toys in the shop.
After $20$ pairs of toys are sold,
$x=80-20=60$ pairs of toys are left
Therefore, $60$ pairs of toys are left in the shop.
Hence, option C is correct.
