    How to calculate the no. of turns of tansformer if i know the voltage of primary and secondary coils only?
    thanks

    You need to specify the primary and secondary currents, voltages and frequency.

    In theory, the ratio of the number of turns in primary:secondary is equal to the ratio of the primary:secondary voltage.

    It is enough to know the active section of the transformer core, input and output voltage, working frequency and the remaining are the calculations. That's I learned in second year high school.
    Come back with the information requested and I'll show you the rest of the calculation.

    Google ARRL handbook archives. They have all the thumb rules for making transformers.
