After interchanging the given two numbers and two signs what will be the values of equation (I) and (II) respectively? ( ) and +, + 3 and 9 I. (7 9-8 2+3 ) II. (4 9-3+8 2 )

Step-by-step solution

According to the question, after interchanging the given two signs and two numbers i.e : - ( ) and + - Two numbers 3 and 9 So, ( aligned & I. 7+3- 8 2 9 & 7+3- 4 9 & 7+3-36 & 10-36 & -26 aligned ) II. (4+3-9 8 2 ) ( 4+3- 9 4 ) ( 4+3 -36 ) ( 7-36 ) ( -29 ) Here, values of equation (I) and (II) are (-26) and (-29) respectively. Hence, "Option - (2)" is the correct answer.
