Anwar's salary is 20% more than Bharat's, and Bharat's salary is 25% less than Chirag's. Anwar's salary is what percent of Chirag's?

Take Chirag's salary as ₹100. Bharat gets 25% less, ₹75, and Anwar gets 20% more than that, $75\times 1.20$ = ₹90 — that is 90% of Chirag's. (Adding and subtracting the percentages as 100 + 20 − 25 = 95 treats both as though they were measured on Chirag's salary. Reading the second sentence backwards, as though Chirag's were 25% less than Bharat's, makes Bharat ₹125 and Anwar ₹150.)
