A. | 8 |

Option: D Explanation : According to given rules we rearrange the given equation which is 90+9-29/10*2 .We will solve it according to BODMAS rule.So firstly we will solve 29/10=2.9 then multiplication 2.9*2=5.8 then 90+9 =99 then 99-5.8= 93.2 . This is not in the options. However,if we simply solve the equation :- firstly 90+9=99 then 99-29=70 then 70/10=7 7*2=14. The correct answer is 'D' Click on Discuss to view users comments.
