Let's Anil's salary be Rs. 100.   Money spent on Rent = 40% of 100 = Rs. 40.   Money spent on medical grounds = 30% of (100 - 40) = 3/10 * 60 = Rs. 18.   Money spent on education = 20% of (60 - 18) = 1/5 * 42 = Rs. 8.40   Anil saves 100 - (40 + 18 + 8.40) i.e., Rs. 33.60   for 33.6 ---&gt; 100 ; 840 ---&gt; ?   Required salary = 840/33.6 * 100 = Rs. 2500   Answer: 2500
