Options

A. `56+12xx34-12=102`
B. `8+44-5+25=203`
C. `112xx44-12+10=46`
D. `9-:64-2xx6=54`

Answer

B

Explanation

Option (1)
`56+12xx34-12=102`
After changing the signs
`56-12-34xx12=102`
or, `56-(12)/(34)xx12ne102`
Option (2) `8+44-5+25=203`
After changing the signs
`8+44xx5-25=203`
or, `8+220-25=203`
or, `228-25=203`
or, `203=203`
Option (3)
`112xx44-12+10=46`
After changing the signs
`112+44xx12-10=46`
or, `(112)/(44)xx12-10=46`
or, `(28)/(11)xx12-10=46`
or, `(336)/(11)-10=46`
or, `(336-110)/(11)=46`
or, `226=46xx11`
or, `226ne506`
Option (4)
`9-:64-2xx6=54`
After changing the signs
`9+64xx2-:6=54`
or, `9+64xx(2)/(6)=54`
or, `9+(64)/(3)=54`
or, `27+64=54xx3`
or, `91ne162`
