Which two signs should be interchanged to make the given equation correct?
`15 div 15 xx 10 -10 + 5 = 15`

Options

A. (a) `div and -`
B. (b) `div and xx `
C. (c) ` xx and -`
D. (d) `+ and -`

Answer

D

Explanation

If we interchange `+ and -` ,
`15 div 15 xx 10 + 10 -5`
`=1 xx 10 + 10-5`
`= 10 + 10 -5`
`=20 -5 `
`=15 ` .
D is correct choice.
