raju was trying to multiply two two- digit numbers, p and q given by his teacher. By mistake he had copied the reverse of the numbers instead of the actual numbers. the number he wrote instead of p was actual 63 less then what is the value of original p?

• p can have three values
  70,81,92.

• suppose no. is 10a+b
  second no is 10b+a
  and condition given as
  10a+b=10b+a+63
  =>10a-a+b-10b=63
  =>9a-9b=63
  =>a-b=7
  so possible values
  a=8,b=1
  a=9,b=2
  so no may be 81 or 92

• let p be 10x+y
  reverse of a no. = 10y+x
  10x+y = 10y+x+63
  9(x-y) = 63
  x-y = 7
  so two answer are 81 n 92

• let p be 10x+y
  10x+y=10y+x+63
  x-y=7
  so numer is 81
