What will come in place of the question mark (?) in the following questions?
$$\frac{21}{25} \times \frac{75}{56} \times \frac{32}{33} = ?$$
Try to see this question with little arrangement to simplify calculation :
= $$\frac{21}{25} \times \frac{75}{56} \times \frac{32}{33}$$ = $$\frac{21}{33} \times \frac{75}{25} \times \frac{32}{56}$$
= $$\frac{7}{11}\times\frac{3}{1}\times\frac{4}{7}$$
= $$\frac{12}{11}$$
= $$1\frac{1}{11}$$
Hence option C is correct
