Solve for `t, 3t - 8 le -t` in the set of whole numbers

A

`0, 1, 2`

B

`1, 2, 3`

C

`0, 1, 2, 3`

D

`1, 2, 3, 4`

Text Solution

Verified by Experts

The correct Answer is:
a
Given, `3t - 8 le -t`
`rArr 3t + t le 8`
`rArr 4t le 8`
`rArr t le 8//4`
`rArr t le 2, " but " t in W`.
`:. T = 0, 1, 2`
Hence, the correct option is (a)
