The income of A and B are in the ratio 5 : 3. The expenses

The income of A and B are in the ratio 5 : 3. The expenses of A, B and C are in the ratio 8 : 5 : 2. If C spends ₹ 2000 and B saves ₹ 700, then A saves

Let the income of A and B be ₹ 5x and ₹ 3x respectively.
Let the expenses of A, B and C
be ₹ 8y, Rs. 5y and ₹ 2y respectively. Then,
2y = 2000

⇒ y =	2000	= 1000
	2

B saves = ₹ 700
∴ 3x –5y = 700
⇒ 3x –5×1000 = 700
⇒ 3x = 700 +5000 = 5700

⇒ x =	5700	= 1900
	3

∴ A’s saving = ₹ (5x–8y)
= ₹ (5×1900–8×1000)
= ₹ (9500 – 8000) = ₹ 1500
