5% of income of A is equal to 15% income of B and 10% income o fB is equal to 20% income of C. If the income of C is ₹ 20,000, then the total income of A, B and C (in thousands if Rs.) is

Solution

let the income of A = x Rs , B = y RS and C = 20000 Rs

given that

x $$\times$$5%} = y $$\times$$ 15% equation 1

and 10% $$\times$$ = 20% $$\times$$ 20000 equation 2

solve eq 2 we get y = 40000 Rs

put value of y in eq 1 we get x= 12000 Rs

so the total income is = 120000 + 40000 + 20000 = 180000 Rs Answer
