Question

when Raju multiplies A certain number by 17 and 4 to the product he gets 225 find the number that number

Answer 1

From Doing Rough, What I understood was your question was adding 4 to the product , and the solution for it is here,

Let the number be x, 

Now according to the question,
17x + 4 = 225, Subtracting 4 on both sides,

=> 17x = 221, Dividing 17 on both the sides,
=> x = 13,

Therefore the number he used was 13,

Hope you understand, Have a great day !

Answer 2

17x+4=225
17x=225-4
17x=221
x=221÷17=13 is the answer
