A man got 10% increase in his salary. If his new salary is ₹ 1,54,000, find his original salary.

Let original salary be ₹ 100.
Therefore New salary i.e., 10% increase = 100 + 10 = ₹ 110
∵ New salary is ₹ 110, when original salary = ₹ 100
∴ New salary is ₹ 1, when original salary = 100/110
∴ New salary is ₹ 1,54,000, when original salary = 100/110 x 154000 = ₹1,40,000
Hence original salary is ₹ 1,40,000.
