A175

B170

C190

D180

D. 180

Read Explanation:

CONCEPT:

Follow BODMAS rule to solve this question, as per the order is given below:


Step-1: Parts of an equation enclosed in 'Brackets' must be solved first and in the bracket,


Step-2: Any mathematical 'Of' or 'Exponent' must be solved next,


Step-3: Next, the parts of the equation that contain 'Division' and 'Multiplication' are calculated,


Step-4: Last but not least, the parts of the equation that contain 'Addition' and 'Subtraction' should be calculated.

CALCULATION:

62×102÷62×62×62=?\frac{6}{2}\times\frac{10}{2}\div{\frac{6}{2}}\times{\frac{6}{2}}\times{6^2}=?

(62)×(106)×36=?(\frac{6}{2})\times(\frac{10}{6})\times{36}=?

(62)×(53)×36=?(\frac{6}{2})\times(\frac{5}{3})\times{36}=?

6×5×6=?6\times{5}\times{6}=?

? = 180
