Which integer should be placed in the box such that the result is 2? `[{(20-18-square) + 2} xx 4] divide 14`

Answer» Correct Answer - 3
`[{(20-bar(18-square)) + 2} xx 4] divide 14 = 2`
`[{20-bar(18-square)) + 2} xx 4] = 28, " since" (28)/(14) = 2`
`{(20-bar(18-square)) + 2} = 7, " since"7 xx 4 =28`
`(20-bar(18-square)) = 5, " since" 5 + 2 = 7`
`bar(18-square) = 15, " since" 20-15 = 5`
`rArr square = 3, " since"18-15 = 3`
`therefore 3 " should be there in the box." `
