Tabular

Answer :

75% of 2568 is required. Divide 2788 in four parts and add three parts.

Thus 2568/4 is 642 and 642*3 = 1926

65% of 2880 is required.

Divide 2880 in ten parts and add six parts and half of 7th part.

Thus 288*6 + 288/2 = 1728 + 144 = 1872

60% of 3575 is required.

Divide 3575 in 5 parts and add three parts.

Thus 3575/5 = 715 and 715*3 = 2145

Average of these three is = [1/3]*[1926+1872+2145] = 1981

Using similar procedures, average of other three is calculated as = 2275

Difference = 2275 - 1981 = 294

Answer :

B = 2880/18 = 1440/9 = 160

C = 2310/14 = 330/2 = 165

D = 3575/22 = 325/2 = 162.5

F = 2788/17 = 164

H = 3360/21 = 480/3 = 160

Highest is in country C.

Answer :

In the year 1994, Number of light commercial vehicles sold were 112

Number of 2-wheelers sold were 442
So,
(112442∗100) = 25.33% (112442∗100) = 25.33%

Answer :

In this question, by referring the table chart, first we need to calculate the increase(in percentage) in sale of Heavy Vehicle in 1994 over 1993

Heavy Vehicle sold in 1993 = 81

Heavy Vehicle sold in 1993 = 107
Increase = 107 - 81 = 26
Now 26 is what percent of 81 ?
(2681∗100)%=32% aprox.

So increase in sale were 32% in 1994,

so get the answer we need to calculate the 132% of 107.
132100∗107=141.24

Answer :

Approx

Required percentage = (8172+79+248+210+404∗100)%

                                  =(811013∗100)%

                                  =7.99%

                                  =8% approx
