Simplify:
​$$62÷5-(\frac{8}9×\frac{18}7)×\frac{7}5+\frac{5}4×\frac{16}{25}$$​​

Correct option is D

Given:
​$$62÷5-(\frac{8}9×\frac{18}7)×\frac{7}5+\frac{5}4×\frac{16}{25}$$​​
Solution:
​$$62÷5-(\frac{8}9×\frac{18}7)×\frac{7}5+\frac{5}4×\frac{16}{25}\\ \ \\ = 62 ÷ 5 - (\frac{16}7) ×\frac{ 7}5 + \frac{5}4 × \frac{16}{25} \\ \ \\ = \frac{62}5 ​-\frac{16}5 ​+\frac{ 5}4​×\frac{16}{25} \\ \ \\ = \frac{62}5 ​-\frac{16}5​+ \frac{4}5 \\ \ \\ = \frac{66}5 - \frac{16}5 \\ \ \\= \frac{50}5 \\ \ \\= 10$$​​
