Saumya has ₹ 24,800 in denominations of ₹500 and ₹100 notes. The number of ₹500 notes is 4 more than the number of ₹100 notes. Find the number of ₹100 notes.
38
Let the number of ₹100 notes be a, so the number of ₹500 notes is a+4.
Total value: \(500(a+4)+100a = 24800\).
\(500a+2000+100a = 24800 \Rightarrow 600a = 22800 \Rightarrow a=38\).
Hence, the number of ₹100 notes is 38.
