= 45
(b) XLIX
= 950 – 10) + 10 – 1)
= 40 + 9
= 45
(c) LVIII
= 50 + 8
= 58
(d) LXXX
= 50 + 10 + 10 + 10
= 80
(e) LXXXVIII
= 80 + 8
= 88
(f) CCXC
= 200 + (100 – 10)
= 290
(g) CCC = 300
(h) D = 500
(i) CMXII
= (100 – 100) + 12
= 912
(j) MMDCXXIX
= 2000 + 500 + 100 + 20 + 9
= 2629
(k) MMXLIII
= 2000 + 50 – 10 + 3
= 2043
(l) MMMDCCCL
= 300 + 500 + 300 + 50
= 3850
Question no – (3)
Solution :
(a) 55 = LV
= (50 + 5) = L + V
= LV
(b) 80 = LXXX
= (50 + 10 + 10 + 10)
= L + X + X + X
= LXXX
(c) 83 = LXXXIII
= (50 + 10 + 10 + 10 + 3)
= L + X + X + X + III
= LXXXIII
(d) 99 = XCIX
= (90 + 9)
= XC + IX
= XCIX
(e) 103 = CIII
= (100 + 3)
= C + III
= CIII
(f) 305 = CCCV
= (100 + 100 + 100 + V)
= C + C + C + V
= CCCV
(g) 600 = DC
= (500 + 100)
= DC
(h) 801 = DCCCI
= (500 + 100 + 100 + 100 + 1)
= D + C + C + C + I
= DCCCI
(i) 1043 = MXLIII
= (1000 + 40 + 3)
= M + XL + III
= MXLIII
(j) 2560 = MMDLX
= 1000 + 1000 + 500 + 60
= M + M + D + L + X
= MMDLX
(k) 3211 = MMMCCXI
= 1000 + 1000 + 1000 + 100 + 100 + 11
= M + M + M + C + C + XI
(l) 3872 = MMMDCCCLXXII
= (3000 + 800 + 70 + 2)
= 1000 + 1000 + 1000 + 500 + 100 + 100 + 100 70 + 2
= M + M + M + D + C + C + C + LXX + II
= MMMDCCCLXXII
Question no – (4)
Solution :
(a) XL/40 < LIII/53
(b) LXXIX/79 < XC/90
(c) XCC III/193 < CXIII/113
(d) CXX/120 > CXIX/119
(e) MC/1900 > LMXXX/1080
(f) CMXXIL < CMCXVII
Question no – (5)
Solution :
(a) M can be repeated thrice – True.
= 1000 + 1000 + 1000
= M + M + M
∴ MMM = 30000
(b) C stands for 100 – True
= C = 100
(c) IX is bigger than X – False.
= IX = 9
= X = 10
(d) 1100 can be written as MC – True.
= 1000 + 100
= M + C
∴ MC = 1100
Question no – (6)
Solution :
(a) XXXIII + XVII = L
(b) LXXX – XXI = LIX
(c) CXXV + CXXIX = CXXIX
(d) CXXI – LXI = LX
(e) LXIII + XXVII/27 = C
Question no – (7)
Solution :
(a) XXXVIII = 38
= XXV = 25
∴ (38 + 25 ) = 63
= 63 = LXIII
Therefore, the sum of XXXVIII and XXV is LXIII.
(b) LXXXVI = 86
XI = 11
∴ (86 + 11) = 97
= 97 = XCVII
Hence, the sum of LXXXVI and XI is XCVII.
(c) XC = 110
CX = 90
∴ (110 – 90) = 20
∴ 20 = XX
Thus, the difference of XC and CX is XX.
(d) XXIII = 23
XXVII = 27
∴ (27 – 23) = 4
∴ 4 = IV
So, the difference of XXIII and XXVII is IV
(e) CC = 200
VI = 6
∴ (200 × 6) = 1200
∴ 1200 = MCC
Therefore, the product of CC and VI is MCC.
(f) LXI = 61
XVII = 17
∴ (61 × 17) = 1037
∴ 1037 = MXXXVII
Thus, the product of LXI and XVII is MXXXVII.
