Direction: The table given below shows the production of maize by 5 different states as a percentage of total production. Each state produces only maize and rice. There are three types of rice - R1, R2 and R3. The table also shows the R1 type of rice produced as a percentage of total rice production and the ratio of R2 and R3 type of rice. Total production by each state is 625000.

A = Average of the R3 type of rice produced by state H, R, S and X together.
B = Difference between the R2 type of rice produced by state T and R1 type of rice produced by state R.
What is the value of K/F? (where K = Average of the total production of R1 type of rice by all the states and F = Total production of R2 type of rice by all the states.)
  • a)
    0.875
  • b)
    0.802
  • c)
    0.080
  • d)
    0.702
Correct answer is option 'B'. Can you explain this answer?

F = Total production of R2 type of rice by all the states.
⇒ F = (6/17 × 0.4 × 0.68 + 9/19 × 0.4 × 0.38 + 3/8 × 0.4 × 0.48 + 4/9 × 0.45 × 0.48 + 3/13 × 0.2 × 0.26) × 625000
⇒ (0.096 + 0.072 + 0.072 + 0.096 + 0.012) × 625000
⇒ 0.348 × 625000
⇒ 217500
K = Average of the total production of R1 type of rice by all the states.
⇒ Total production of R1 type of rice by all the states = (0.6 × 0.68 + 0.6 × 0.38 + 0.6 × 0.48 + 0.55 × 0.48 + 0.8 × 0.26) × 625000
⇒ (0.408 + 0.228 + 0.288 + 0.264 + 0.208) × 625000
⇒ (1.396) × 625000
⇒ 872500
⇒ K = 872500/5 = 174500
∴ K/F = 174500/217500 = 0.802

⇒ R3 type of rice produced by state H = 11/17 × 0.4 × 0.68 × 625000 = 110000
⇒ R3 type of rice produced by state R = 10/19 × 0.4 × 0.38 × 625000 = 50000
⇒ R3 type of rice produced by state S = 5/9 × 0.45 × 0.48 × 625000 = 75000
⇒ R3 type of rice produced by state X = 5/8 × 0.4 × 0.48 × 625000 = 75000
⇒ A = Average of the R3 type of rice produced by state H, R, S and X together
⇒ A = (110000 + 50000 + 75000 + 75000) /4 = 77500
⇒ R2 type of rice produced by state T = 3/13 × 0.2 × 0.26 × 625000 = 7500
⇒ R1 type of rice produced by state R = 0.6 × 0.38 × 625000 = 142500
⇒ B = Difference between the R2 type of rice produced by state T and R1 type of rice produced by state R.
⇒ B = 142500 - 7500 = 135000
∴ B - A = 135000 - 77500 = 57500

Direction: The table given below shows the income and expenditure (in Rs) of two companies A and B form 2012 to 2016.

    2016
  • c)
    2015
  • d)
    2012
Correct answer is option 'D'. Can you explain this answer?

Naveen Iyer answered
Profit percentage of B for 2012 = (180000 - 150000)/150000 × 100 = 20%
Profit percentage of B for 2013 = (250000 - 220000)/220000 × 100 = 13.64%
Profit percentage of B for 2014 = (320000 - 300000)/300000 × 100 = 6.67%
Profit percentage of B for 2015 = (375000 - 350000)/350000 × 100 = 7.14%
Profit percentage of B for 2016 = (450000 - 400000)/400000 × 100 = 12.5%
The profit percentage of B for 2012 is the highest

    45.45
  • b)
    52.52
  • c)
    42.5
  • d)
    39.5
Correct answer is option 'A'. Can you explain this answer?

Naveen Iyer answered
Quantity of rice produced by state X = 0.48 × 625000 = 300000
⇒ (R2 and R3) type of rice produced by state X = 300000 × 0.40 = 120000
⇒ R3 type rice produced in state X = 5/8 × 120000 = 75000
And
⇒ Quantity of rice produced by state S = 625000 × 0.48 = 300000
⇒ R1 type rice produced in state S = 300000 × 0.55 = 165000
∴ Required percentage = (75000/165000) × 100 = 45.45%
A = Average of the R3 type of rice produced by state H, R, S and X together.
B = Difference between the R2 type of rice produced by state T and R1 type of rice produced by state R.

Direction: The table given below shows the production of maize by 5 different states as a percentage of total production. Each state produces only maize and rice. There are three types of rice - R1, R2 and R3. The table also shows the R1 type of rice produced as a percentage of total rice production and the ratio of R2 and R3 type of rice. Total production by each state is 625000.

A = Average of the R3 type of rice produced by state H, R, S and X together.
B = Difference between the R2 type of rice produced by state T and R1 type of rice produced by state R.
What is the sum of the total production of maize by state X and T and total production of R2 type of Rice by state S and R?
  • a)
    868500
  • b)
    1025000
  • c)
    925000
  • d)
    892500
Correct answer is option 'D'. Can you explain this answer?

Total production of maize by state X and T = 625000 × (0.52 + 0.74) = 787500
Now
⇒ Quantity of rice produced by state S = 625000 × 0.48 = 300000
⇒ (R2 and R3) type of rice produced by state S = 300000 × 0.45 = 135000
⇒ R2 type of rice produced in state S = 4/9 × 135000 = 60000
And
⇒ Quantity of rice produced by state R = 625000 × 0.38 = 237500
⇒ (R2 and R3) type of rice produced by state R = 237500 × 0.4 = 95000
⇒ R2 type of rice produced in state R = 9/19 × 95000 = 45000
⇒ Total production of R2 type of Rice by state S and R = 60000 + 45000 = 105000
∴ Required sum = 787500 + 105000 = 892500

Directions: Study the following table and answer the questions: Population of a locality from 1988 to 1992
Number of children in 1989 is:
  • a)
    25670
  • b)
    56740
  • c)
    52297
  • d)
    62957
Correct answer is option 'A'. Can you explain this answer?

∵ Total population in 1988 = 146947
∵ Increase in population in 1989 over preceding year = 11630
∵ Total population in 1989 = 146947 + 11630 = 158577
∴ Number of children in 1989 = 158577 – (70391 + 62516) = 25670

Directions: Study the following table and answer the questions: Population of a locality from 1988 to 1992
Number of women in 1991 is:
  • a)
    57630
  • b)
    56740
  • c)
    52297
  • d)
    62957
Correct answer is option 'A'. Can you explain this answer?

∵ Total population in 1990 = 153922
∵ Decrease I population in 1991 over the preceding year = 5337
∵ Total population in 1991 = 153922 – 5337 = 148585
∴ Number of women in 1991 = 148585 – (69395 + 21560) = 57630
