यदि "P"का अर्थ "गुणा " है,"R" का अर्थ " घटाव" है,"S" का अर्थ "जोड़ "है तथा "Q" का अर्थ " भाग "है , तो निम्नलिखित में से कौन सा समीकरण सही है ?

Options

A. `18" "R" "60" "Q" "15" "S" "2" "=" "8`
B. `15" "S" "16" "Q" "2" "P" "4" "= 47`
C. `3" "P""5" "R" "18" "Q" "3" "= 6`
D. ` 15" "S" "28" "Q" "4" "P" "2" "=27`

Answer

B

Explanation

`{:(PrArrxx,RrArr-),(SrArr+,QrArrdiv):}`
विकल्प (1)
`18" "R" "60" "Q" "15" "S" "2 = 8`
`rArr 18 - 60 div 15 + 2 = 8`
`rArr 18 - 4 + 2 = 8`
`rArr 20 - 4 = 8`
`rArr 16 ne 8`
विकल्प (2)
`15" "S" "16" "Q" "2" "P" "4=47`
`rArr 15 + 16 div 2 xx 4 = 47`
`rArr 15 + 32 = 47`
`rArr 47 = 47`
विकल्प (3)
`3" "P" "5" "R" "18" "Q" "3 = 6`
`rArr 3 xx 5 - 18 div 3 = 6`
`rArr 15 - 6 = 6`
`rArr 9 ne 6`
विकल्प (4)
`15" "S" "28" "Q" "4" "P" "2 = 27`
`rArr 15 + 28 div 4 xx 2 = 27`
`rArr 15 + 14 ne 27`
`rArr 29 ne 27`
