The sum of 5/8 and 8/5 is :

The standard deviation of data 6,5,9,13,12,8 and 10 is

In the following number series how many such 8s are there which are immediately preceded by a pair or number whose product is more than the product of pair of of numbers immediately following 8 ? "5 3 8 2 4 5 8 3 1 9 7 4 9 6 8 5 7 8 6 5 8 4 7 5 2 8 8 3 3 5 4 2 8 6 5 3 7 8 5 9 8 7"

5 – ( – 8) is same as 5 + 8.

Represent 8/5 and (-8)/5 on the number line.
