      @mbatious At the time of meeting, Let the distance travelled by first train be X Let the distance travelled by second train be x+60 Given, Speed of fist train = 16km/hr Speed of second train =21km/hr Since they begin at the same time and meet each other, x/16=(x+60)/21 ~x=192 km Total Distance= x+60+x =444km

      @hemant_malhotra Hello sir, To the reference of the above question, I have a doubt. It says he makes 20% profit secretly and claims to sell at the 10% loss. Then, If cost price is 100 , he makes a loss of 10 I.e. 90(S.P.) but here he SECRETLY makes a profit of 20%. So won't that be 90/1.2?

      @Rowdy-Rathore F(x) = x^4-360x^2+400F(x) = (x^2+20)^2 - 400x^2F(x) = (x^2-20x+20)(x^2+20x+20) = Prime NumberSince the value of second factor is always positive and greater than 1 therefore, 1st factor hasto be equals to 1.x^2-20x+20 = 1x^2-20x+19= 0On solving,x = 1, 19.Putting back the values in the original equation we get f(x) = 41 and f(x) = 761. So, the sum will be 41+761 = 802

      @master_shifu If both y and x are zero, then xy + yz + xz would be equal to zero. The answer stated by you is wrong.
