Question

85+43×(627)\frac{8}{5} + \frac{4}{3} \times \left( 6 - \frac{2}{7} \right)​​

A.

968105\frac{968}{105} ​​

B.

6215\frac{62}{15}​​

C.

5815\frac{58}{15}​​

D.

11635\frac{116}{35}​​

Correct option is A

1. Simplify 6 - 27\frac{2}{7}​ :

6=427,so 627=42727=4076 = \frac{42}{7}, \quad \text{so } 6 - \frac{2}{7} = \frac{42}{7} - \frac{2}{7} = \frac{40}{7}


2. Multiply 43by407\frac{4}{3} by \frac{40}{7} ​:

43×407=16021\frac{4}{3} \times \frac{40}{7} = \frac{160}{21}​.


3. Add 85and16021\frac{8}{5} and \frac{160}{21} ​:
- Convert 85\frac{8}{5}​ to have a common denominator with 16021\frac{160}{21}​ :

85=168105,16021=800105\frac{8}{5} = \frac{168}{105}, \quad \frac{160}{21} = \frac{800}{105}​.

- Add:

168105+800105=968105\frac{168}{105} + \frac{800}{105} = \frac{968}{105}​.


4. Simplify the result:

968105=923105\frac{968}{105} = 9 \frac{23}{105}


Final Answer:
The correct answer is 968105\frac{968}{105}
