Question

When Jojo's mother asked how many toys Jojo had, naughty Jojo told her that if she bought him 8 more toys, he would have 20. What is the equation that would help us to find the number of toys Jojo had?

• A. $x+8=20$
• B. $x-8=20$
• C. $x+8=-20$

Answer 1

The correct option is A $x+8=20$

Let '$x$' denotes the number of toys Jojo had.

If Jojo's mother bought him 8 more toys, Jojo would have total 20 toys.
$\Rightarrow x+8=20$

Suppose Jojo had a dozen toys, i.e., 12 toys.
If this satisfies the above equation then the assumption is correct.
$x+8=20$
$\Rightarrow 12+8=20$
$\Rightarrow 20=20$
$\Rightarrow$ Left hand side = Right hand side

Hence, the assumption that Jojo had 12 number of toys is correct.
