Observe the given equation. Identify the missing number in the box.

A)  \[15\]                           

B)         \[40\]                 

C)         \[25\]                           

D)         \[5\]

Correct Answer: C

Solution :

\[\frac{5}{6}\times 15=\frac{?}{12}\times 30\] On cancelling the factors common to numerator and denominator on both the sides,             \[\frac{5\times 5}{2}=\frac{{}}{2}\times 5\]             \[5\times \frac{5}{2}=\_\_\times \frac{5}{2}\] Hence the missing number is\[5\].
