15% of X = 20% of Y = 30% of Z, X + Y + Z = 9000, Y spends 2200.
Solution:
Let 15% of X = 20% of Y = 30% of Z = k.
Then, X = k/0.15, Y = k/0.20, Z = k/0.30.
Substituting in X + Y + Z = 9000, we get k = 600.
Then, Y = k/0.20 = 600/0.20 = 3000.
Y's saving = Y's income - Y's expenditure = 3000 - 2200 = 800.
Therefore, Y's saving is ₹800.
