यदि `''theta''`का अर्थ "जोड़" है,`''delta''` का अर्थ " घटाव" है,`''beta''` का अर्थ " भाग "है तथा `''alpha''` का अर्थ "गुणा "है , तो
` 5 " "beta" "1" "delta" "9" "alpha" "7" "theta" "142" "= ?`

Options

A. 114
B. 98
C. 84
D. 125

Answer

C

Explanation

`{:(thetarArr+,deltarArr-),(beta rArr div,alpharArrxx):}`
`5" "beta" "1" "delta" "9" "alpha" "7theta" "142 = ?`
`rArr 5 div 1 - 9 xx 7 + 142`
`rArr 5 div 1 - 9 xx 7 + 142`
`rArr 5 - 9 xx 7 + 142`
`rArr 147 - 63 = 84`
