25) B

The key to answering this question is realising that no charity will receive more than \$100.

STARS will receive the second highest amount of money. We have no information about what the other charities will receive. We are given 5 options for what STARS’s least amount would be.

There will be three charities that will receive less money than STARS. We must use the options provided to work out the answer. By using each option, we must use the maximum amount that the remaining 3 charities will get.

If STARS obtained \$25, we must assume that the 3 charities will get \$24, \$23 and \$22.

This gives us a total of \$94 (25 + 24 + 23 + 22). This means that the remaining 5th charity will get:
\$200 – \$94 = \$104

However, this does not satisfy the condition that no charity can receive more than \$100. So A is wrong.

If START obtained \$27, the 3 charities will get \$26, \$25, \$24.
Total = \$102
5th charity will get = 200 – 102 = \$98

So \$27 is the least amount that can be given to STARS. So B is the answer.
