What will be the value of the following equation if `div` means 'addition', + means 'subtraction', '-' means 'multiplication' and '`xx`' means 'division'?
/निम्नलिखित समीकरण का मान क्या होगा यदि `div` का अर्थ जोड़, + का अर्थ घटाव, ‘-’ का अर्थ गुणा एवं ‘`xx`’ का अर्थ भाग है ?
`54 xx 6- 7 div 8 + 2 =?`

Options

A. 57
B. 69
C. 63
D. 61

Answer

B

Explanation

`{:("Symbol",div,+,-,xx),("Meanin",+,-,xx,div):}`
`54 xx 6 - 7 div 8 + 2 = ?`
After changing the symbols,
`54 div 6 xx 7 + 8 - 2`
(Applying BODMAS rule)
`implies 9 xx 7 + 8 – 2`
`implies 63 + 8 - 2`
`implies 71 – 2`
`implies 69`
ence, option (b) is correct.
