Find the ratio of `^20 C_ra n d^(25)C_r` when each of them has the greatest possible value.

Text Solution

Verified by Experts

The correct Answer is:
`143//4025`
Maximum value of `.^(20)C_(r ) " is" .^(20)C_(10)` and maximum value of `.^(25)C_(r )`is `.^(25)C_(12)`. Hence, the required ratio is `.^(20)C_(10)//^(25)C_(10)=143//4025`.
