Which two signs should be interchanged to make the given equation correct?
16−4+2×15÷5=29

Let's check Option C (× and −):
Interchanging − and × in the original expression gives:

16×4+2−15÷5
Now solve using BODMAS rules:

Division: 15÷5=3

Expression becomes: 16×4+2−3
Multiplication: 16×4=64

Expression becomes: 64+2−3
Addition and Subtraction:

66−3=63

=29
This is incorrect. Let's test Option B (+ and ×):

16−4×2+15÷5
Division: 15÷5=3

16−4×2+3
Multiplication: 4×2=8

16−8+3
Addition/Subtraction:

16−8+3=8+3=11

=29
This is incorrect. Let's test Option A (÷ and −):

16÷4+2×15−5
Division: 16÷4=4

4+2×15−5
Multiplication: 2×15=30

4+30−5
Addition and Subtraction:

34−5=29
The LHS equals RHS (29=29). Thus, interchanging ÷ and − makes the equation correct.
