If the original total deposit of two people is 1, naughty deposits account for 8/ 15, and smiles account for 7/ 15.

After the naughty withdrawal of 25%, the remaining deposits account for 8/ 15×( 1-25%)=2/5 of the total.

Because less deposit in 50 yuan is more naughty than 90 yuan, less deposit in 50 yuan is more naughty than 90-50 after cash withdrawal. 25% = 40 yuan.

So the result is that the total deposit of two people is 40÷[7/ 15-2/5]=600 yuan.

Xiaoxiao's original deposit is 600x 7/ 15=280 yuan, and naughty original deposit is 600-280=320 yuan.

Xiaoxiao's current deposit is 280+50=330 yuan, and naughty current deposit is 320x75%=240 yuan.

1 Smile The original deposit is 280-240 more than the current naughty bag deposit = 40 yuan.

2 The ratio of the naughty boy's current deposit to Xiaoxiao's original deposit is 240: 280 = 6: 7.

The original deposit of the naughty boy was 320 yuan. (For the process, see above)
