Answer:
CPI for the current year = 200
Explanation:
Given;
Contents in market basket
20X, 30Y, and 50Z
The current-year prices for goods
X = $2
Y = $6
Z = $10
The base-year prices are
X = $1
Y = $3
Z = $5
Now,
Total cost of market basket in the current year
= ∑ (Quantity × Price)
= 20 × $2 + 30 × $6 + 50 × $10
= $40 + $180 + $500
= $720
Total cost of market basket in the base year
= ∑ (Quantity × Price)
= 20 × $1 + 30 × $3 + 50 × $5
= $20 + $90 + $250
= $360
also,
CPI for the current year =
or
CPI for the current year =
or
CPI for the current year = 200
