Step by step with no step skipped solution has been given........still you didn't get it???
See:
let ratio be x.
Hence no. of coins be 5x ,9x , 4x respectively
Now given total amount = Rs. 412
=> (.50)(5x) + (.25)(9x) + (.10)(4x) = 412

find x and put the value of x in 4x to get the number 10p coins.
