. When numbers are written in base of b , we have 12*15=333. What is the value of b?

• If it is 12*25=333
  then base is 7.
  9*19 =171 which is 333 in base 7.

• b has to be 6 or greater than 6.
  But in no case
  12*15=333 is satisfied.
  
  so given data is wrong.

• the ques is wrong ..it should be 12*25=333....then the solution would have been b=7...because...25*12=300 when base is 10...and here it is 333..so definitely b should be less than 10...keep on checking for b=9,8,7...finally at b=7 u will get, (2*7^0+1*7^1)*(5*7^0+1*7^1)=333

• 12*25=333
  (b+2)(2b+5)=3b^2+3b+3
  b^2-6b-7=0
  (b+1)(b-7)=0
  b!=-1
  therefore b=7
