यदि `13" "L" "4" "A" "7 = 41"तथा" 14" "A" "3" "L" "12 = 54` हो , तो `12" "L" "3" "A" "9 = ?`

Options

A. 84
B. 39
C. 42
D. 56

Answer

B

Explanation

`13" "L" "4" "A" "7 = 41`
`rArr 13 + 4 xx 7 = 41`
`rArr 13 + 28 = 41`
इस प्रकार 'L' का अर्थ है '+' तथा 'A'का अर्थ है `'xx'`.
`14" "A" "3" "L" "12 = 54`
`rArr 14 xx 3 + 12 = 54`
`rArr 42 + 12 = 54`
अतः ,
`12" "L" "3" "A" "9 = ?`
`rArr ? = 12 + 3 xx 9`
`rArr ? = 12 + 27 = 39`
