A) \[\div \,and\,-\]
B) \[+\,and\,-\]
C) \[\times \,and\,-\]
D) \[\div \,and\,-\]
E) None of these
Correct Answer: C
Solution :
Explanation Option [c] is correct. After changing the signs the equations will be: [a] \[25-5+17\times 2\div 6\] \[25-5+\frac{17}{3}\] (the answer will be in fractions whereas 10 is a whole number, so no further calculation) [b] \[25\div 5-17\times 2+6\] \[5-34+6=-23\] which is wrong [c] \[25\div 5+17-2\times 6\] \[5+17-12=10\] which is correct [d] \[25+5\div 17\times 2-6\] \[\text{(5 }\!\!\div\!\!\text{ 17}\,\text{gives}\,\,\text{the}\,\text{answer}\,\text{as}\,\,\text{in}\,\text{(A)}\,\text{)}\].
