What is the scope including 1/61+1/62+1/63+......+1/70? Choose the correct answer.
A) 1/7~1/6 B) 1/5~1/4 C) 1/4~1/3 D) 1/3~1/2 E) 1/2~1
For Maximum value : It should be less than 1/61 + 1/61 +1/61... 10 times = 10/61 ~ 1/6   For Minimum Value : It should be greater than 1/70+ 1/70+ 1/70 .. 10 times = 10/70 = 1/7   Thus, the answer should lie between 1/7 and 1/6. Correct ans : 1/7~1/6.
