Directions (1-5):

Let number of chairs, tables and wardrobes sold by A in August be 42x, 36x and 23x. Also, let chairs sold by A in August, September and October be 14y, 23y and 27y respectively.

∴42x = 14y ⇒y = 3x

and, 23x = 23y – 230

⇒x = 5 and y = 15

Now,

Chairs sold by B in September = 665 – 345 = 320

Chairs sold by B in August = 320

Tables sold by B in September = Chairs sold by A in Aug = 210

∴Table sold by A in September = 400 – 210 = 190

Wardrobes sold by B in September = wardrobes sold by A in Aug = 115

∴Wardrobes sold by A in September = 210 – 115 = 95

Chairs sold by B in October = 1025 – 320 – 320 = 385

Tables sold by A in October = (1025 – 480) – (180 + 190) = 175

Tables sold by B in August = (11/12) × 180 = 165

Tables sold by B in October = (38/35) × 175 = 190

Wardrobes sold by B in August = 1075 – (210 + 320 + 180 + 165 + 115) = 85

Let wardrobes sold by A in October be a and that by B be b in October

∴a = b – 35 and a + b = 205

⇒a = 85 and b = 120 Required Ratio = 180/210 = 6/7

Wardrobes sold by B in Oct = 120

Required difference = 320 – 210 = 110

Total chairs sold by B in September and October = 320 + 385 = 705

[(175-120)/120] * 100 = 45.83%

Direction (6-10) :

Invalid voter of village C in 2005 = 4000 * 36/64 = 2250

Valid voter of village C in 2001 = 4000 * 19/25 = 3040

Now, invalid voter of village C in 2001 = 3040 * 24/76 = 960

∴Required diff. = 2250 – 960 = 1290

Total valid votes of village A in 2005 = 2500 * 100/20 * 80/100 = 10000

Total valid votes excluding Nota in village A in 2005 = 10000 * 90/100 = 9000

∴According to question,

x + (x + 200) = 9000

⇒x = 4400

Required no. of votes of losing candidates = 4400

Let the total voters in 2005 are x.

Total voters in 2001 = (26/23) x

∴ [x * 26/23 * 25/100] / [x * 35/100] = 130/161

Total invalid male of village E in 2001

= 2000 – 1600 = 400

Total valid voters in 2001 = 1600 * 100/64 = 2500

Total Voters in 2001 = 2500 * 100/80 = 3125

∴ required % = (400/3125) * 100 = 12.8 %

Let total voters of village B in 2001 = x

& Total voters of village D in 2005 = y

∴ [x * 75/100]/ [y * 30/100] = 16/3

x/y = 32/15

Required % = 17/32 * 100 = 53 1/8 %
