After interchanging the given two signs what will be the values of equation (I) and (II) respectively?
× and ÷
I. 16 × 4 – 8 ÷ 2 + 20
II. 35 ÷ 7 × 5 + 15 - 18

Correct option is C

We need to interchange the signs multiplication (×) and division (÷) in the given equations and calculate the new values of the equations.
Given Equations:
1. 16×4−8÷2+20
2. 35÷7×5+15−18
After interchanging × and ÷: (I). New equation:
=16÷4−8×2+20
=4 - 16 + 20
= 24 – 16
= 8 After interchanging × and ÷: (II). New equation:
=35×7÷5+15−18
= 7×7 + 15 – 18
= 49 + 15 – 18
= 64 – 18
= 46
Now, values of equations I and II are 8 and 46 respectively.
Thus, correct option is (c).
