• Price of 1 plastic spoon is 5 rupees.
• Total money he spend is ₹38.

Let the number of plastic boy is x.

Let the number of plastic spoon is y.

$= > 7x + 5y = 38$

There is only one possibility for which the above sum is ₹38 when x=4 and y=2.

$= > 7 \times 4 + 5 \times 2 = 38$

So the number of plastic toy he purchase is 4.
