Show answer & explanation
Correct answer: C
CONCEPT
When exports : imports = a : b and exports E is known, imports are E × b/a.
Apply the ratio to each country separately before adding the imports.
APPLICATION
From the table, country D exported ₹90 crore in 2019. Since exports : imports = 1 : 2, D imports = 90 × 2/1 = ₹180 crore.
From the table, country F exported ₹48 crore in 2019. Since exports : imports = 4 : 1, F imports = 48 × 1/4 = ₹12 crore.
Total imports of D and F = 180 + 12 = ₹192 crore.
CROSS-CHECK
The recovered ratios are 90 : 180 = 1 : 2 and 48 : 12 = 4 : 1. Their imports add to ₹192 crore.
RESULT
Therefore, the required total import is ₹192 crore.
