Answer» 60Putting the given values in L.H.S.,5 x 10 = 50, 5 x 5 = 25∵ L.H.S. ≠ R.H.S. ∵ L.H.S.≠ R.H.S.∴m=10 is not the SOLUTION. ∴m=5 is not the solution.5 x 12 = 60, 5 x 15 = 75∵ L.H.S. = R.H.S. ∵ L.H.S. ≠ R.H.S.∴m=12 is a solution. ∴m=15 is not the solution.(b) n+12=20Putting the given values in L.H.S.,12 + 12 = 24, 8 + 12 = 20∵ L.H.S. ≠ R.H.S. ∵ L.H.S. = R.H.S.∴n=12 is not the solution. ∴n=8 is a solution.20 + 12 = 32, 0 + 12 = 12∵ L.H.S. ≠ R.H.S. ∵ L.H.S. ≠ R.H.S.∴n=20 is not the solution. ∴n=0 is not the solution.(C) p–5=5Putting the given values in L.H.S.,0 – 5 = –5, 10 – 5 = 5∵ L.H.S. ≠ R.H.S. ∵ L.H.S. = R.H.S.∴p=0 is not the solution. ∴p=10 is a solution.5 – 5 = 0, –5 – 5 = –10∵ L.H.S. ≠ R.H.S. ∵ L.H.S. ≠ R.H.S.∴p=5 is not the solution. ∴p=–5 is not the solution. |
