Answer:

The correct option is (a).

Explanation:

We need to find the product of given numbers.

First number = 29.5

Second number = 240

Product of two numbers = 29.5 × 240

= [tex]\dfrac{295}{10}\times 240[/tex]

Zeroes from numerator and denominator get cancelled.

So,

[tex]=295\times 24\\\\=7080[/tex]

Hence, the correct option is (a).
