If 60% of A’s income is equal to 75% of B’s income,

If 60% of A’s income is equal to 75% of B’s income, then B’s income is equal to y% of A’s income. The value of y is :

Let A’s income = ₹ a and B’s income = ₹ b
a × 60% = b × 75%
∴ a × 4 = 5 × b

⇒	b	=	4
	a		5

Now, b = a × y%

⇒	b	=	y
	a		100

⇒	y	=	4
	100		5

⇒ y =	4	× 100 = 80
	5
