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.)
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

What is the value of B  A?
⇒ 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

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.
Production of R3 type of rice by state X is what percentage of production of R1 type of rice by state S?
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.
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?
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

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 difference between the R1 type of rice produced by state X and the R2 type of rice produced by state H?
Rice produced by state X = 48% and that of by state H = 68%
⇒ Quantity of rice produced by state X = 0.48 × 625000 = 300000
⇒ R1 type of rice produced by state X = 300000 × 0.6 = 180000
Now
⇒ Quantity of rice produced by state H = 0.68 × 625000 = 425000
⇒ R1 type of rice produced by state H = 425000 × 0.6 = 255000
⇒ Remaining quantity of rice = 425000  255000 = 170000
⇒ R2 type of rice produced by state H = 6/17 × 170000 = 60000
∴ Required difference = 180000  60000 = 120000
