answer quick pls

Answer 1

Given:

A car driver fills
`10(1)/(2)\text{ kg}` of CNG and paid Rs. 1995.

To find:

The cost of 1 kg of CNG.

Solution:

According to the given information,

The cost of
`10(1)/(2)\text{ kg}` of CNG = 1995 rupees

Using this information, we get

The cost of 1 kg of CNG =
`(1995)/(10(1)/(2))` rupees

=
`(1995)/((20+1)/(2))` rupees

=
`(1995)/((21)/(2))` rupees

=
`1995* (2)/(21)` rupees

=
`190` rupees

Therefore, the cost of 1 kg of CNG is 190 rupees.
