### Problem 7

1. 1. UTM<br /> BCA<br />Tank X, Y and Z each contained some water. Tank X contains 3 times as much water as Tank Y. After 15% of the water in Tank X and 15% of Tank Y was poured in Tank Z, Tank Z had 30% more than before. If Tank Z had 104 litres of water, how many litres of water had Tank X at first ?<br />
2. 2. Tank X, Y and Z each contained some water. Tank X contains 3 times as much water as Tank Y. After 15% of the water in Tank X and 15% of Tank Y was poured in Tank Z, Tank Z had 30% more than before. If Tank Z had 104 litres of water, how many litres of water had Tank X at first ?<br /> UTM<br /> BCA<br />Step 1<br />
3. 3. Tank X, Y and Z each contained some water. Tank X contains 3 times as much water as Tank Y.
