Question 52

The given table represents the exports (in ₹crores) of four items A, B, C and D over a period of six years. Study the table and answer the question that follows.

In which year, the exports of item D were 1.4 times the average exports of item B during six years?

Solution

Average exports of item B during six years = $$\frac{128 + 134 + 138 + 169 + 182 + 209}{6}

(Average = sum of the terms/no. of terms)

= 960/6 = 160

1.4 times the average exports of item B during six years = 1.4 $$\times$$160 = 224

In year 2013, the exports of item D were 1.4 times the average exports of item B during six years.
