Observe that in the equation .

Hence *x* has to be negative number. Also because the denominators are 3 and 5, the denominator of x will be LCM of 3 and 5, i.e. 15. Since only option ‘4’ satisfies the conditions of the denominator being negative as well as =15, it should be the answer.

**(Ans: 4)**

*Estimated Time to arrive at the answer = 10 seconds.*
