Answer:
B. 70
Step-by-step explanation:
We have the sum given by
Now, we open the summation by substituting the values of 'i',
i.e. = (1+11) + (2+11) + (3+11) +(4+11) +(5+11)
i.e. = 12 + 13 + 14 + 15 + 16
i.e. = 70.
Hence, the sum of is 70.
So, option B is correct.
The least common multiple of 5 and 10 is 10. Convert 4/5 and 9/10 to fractions with denominators of 10.
Since 8/10 and 9/10 have the same denominator, join their numerators to add them.
