240 = ?*
7080
71
7100
8000

Answer 1

The correct option is (a).

Step-by-step explanation:

We need to find the product of given numbers.

First number = 29.5

Second number = 240

Product of two numbers = 29.5 × 240

=
`(295)/(10)* 240`

Zeroes from numerator and denominator get cancelled.

So,

`=295* 24\\\\=7080`

Hence, the correct option is (a).
