16% of Doctors in Borough IV, Ward 128 in Kolkata have their mother-tongue as Tamil

As the ratios are given to be the same,

16% of Professors too in Borough IV, Ward 128 in Kolkata have their mother-tongue as Gurumukhi

From the last question,

The number of Doctors in Borough IV, Ward 128 in Kolkata = 180

Thus 18% of the adult population = 180

Professors were 15% of the adult population

So 15% of the adult population = (180/18)*15 = 150

Thus, the number of Professors in Borough IV, Ward 128 in Kolkata = 150

Hence, the number of Professors who have Gurumukhi as their mother-tongue

= 16% of 150

= (16*150)/100

= 24
