Which two signs should be interchanged in the following equation to make it correct 868 14 times 55 ...........

Explanation:

Given 
868+14×55 - 1064÷56 
now solving the equation using BODMAS 
868+14×55-19
868+770-19
=1617
but according to question we have 868+×55 - 1064÷56 = 117
hence the difference between the answers is 1617-117 = 1500 
so we need to substract 1500 from the equation to get the correct values which can be done by replacing the sign of plus "+" with that of minus "-"
so that the equation gets corrected i.e 868-770+19 is 117.

Hence option 3 is the correct answer.
