Solutions:

51.6% = 7224

50.4% = 7056

53.2% = 7448

14.6% = 2044

19.2% = 2688

x + k = 7224 – (2044 + 1904) = 3276 ––––– (I)

z + k = 7448 – (2044 + 2688) = 2716 –––––– (II)

y + z + k = 7056 – 1904 = 5152 –––––––––– (III)

x + y + z + k = 14000 – (2044 + 1904 + 2688) = 7364 –– (IV)

equn (IV) – equn (III)

x = 7364 – 5152 = 2212

From equn (I) k = 3276 – 2212= 1064

From equn (II) z = 2716 – 1064 = 1652

From equn (III) y = 5152 – 2716 = 2436

2. 1064/14000 × 100 = 7.6%

3. 7224-2212=5012

4. 1652/14000 x 100 = 11.8%

5. At least two language = 1904 + 2044 + 1652 + 1064 = 6664

So, 6664/14000 x 100 = 47.6%
