Kelly gbe 34 kilogiramu, eyi ni 15% kekere lati Megan. Mike gbe 5 kilogiramu ju Megan. Ki o le ri pe awon omo meta won gbe ni oke lati lo, ki o tobi ju kilogiramu won ni won gbe ni oke?" <response>: ```If Kelly weighs 15% less than Megan, this means Kelly's weight is 100 - 15 = 85% of Megan's weight.
85% is 0.85, so Megan weighs 34 / 0.85 = 40 kilograms.
Mike weighs 5 kilograms more than Megan, so he weighs 40 + 5 = 45 kilograms.
In total all three kids weigh 34 + 40 + 45 = 119 kilograms.
That means to cross the bridge safely, they weigh 119 - 100 = 19 kilograms too much.

The final answer: 19.```
