A sum of ₹53,000 is divided among A, B, and C such
that A gets 20% more than B, and B gets 25% less than C. What is the amount received by C?Solution
Let the amount received by C be ₹x. Amount received by B = 75% of C = (75/100)x = 0.75x. Amount received by A = 120% of B = (120/100)(0.75x) = 0.9x. Total amount = A + B + C = 53,000. 0.9x + 0.75x + x = 53,000. 2.65x = 53,000. x = 53,000 / 2.65 = ₹20,000 Correct Option: a
