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

= $\dfrac{295}{10}\times 240$

Zeroes from numerator and denominator get cancelled.

So,

$=295\times 24\\\\=7080$

Hence, the correct option is (a).
