Let total number of ₹5 coin be x, ₹2 coins be y and ₹1 coins be z.

So, we will have two equations

5x + 2y +z = 100 ..---(1)

x + y + z = 40....(2)

From eqn (1) and (2) -

4x + y = 60

So now checking with option

When x = 16 => y = -4 (not possible)

So, the value should be less than 16, which is 13.

Hence, option 4 is correct.
