Correct Answer: D
Solution :Let probability of passing in English and Math are P & P (B). Then, here \[P\,\,(A)=60%\] \[P\,\,(A\cap B)=54%\] \[P\,\,(A\cap B)=P\,\,(A)\times P\,\,(B)\] \[54=60\times P\,\,(B)\] \[\Rightarrow \] \[P\,\,(B)=0.9\] \[P(B)=90%\] Hence, the % probability that he will fail in Maths \[=P\,\,(B)\] \[=100-90\] = 10%
