Income Ratios of Four Persons

Let Biren's income $= x$, Deepak's income $= 2x$. Anand's income $= x + 140$. Chandu's income $= 2x + 80$.

Given ratio of Anand to Chandu $= 2 : 3$: $\frac{x + 140}{2x + 80} = \frac{2}{3} \implies 3x + 420 = 4x + 160 \implies x = 260$

Incomes:

• Anand $= 260 + 140 = ₹400$
• Biren $= ₹260$
• Chandu $= 2(260) + 80 = ₹600$
• Deepak $= 2(260) = ₹520$
