Let the Original sum is Rs x

So according to the question ,

After 5% of deduction we get , x - 5x/100 = 19x/20 and

again 10 % deduction we get ,

19x/20 - 19x/20 x 10/100

= 19x/20 - 19x/200

= (190x-19x)/200

= 171x/200

and it is given as , 171x/200 = 171

So x = 200

So, The original sum was Rs 200
