Question 15

EasyOriginal question

A two-wheeler maker studies its monthly sales from 2010 to 2025. It notes four features: sales jump every October and November in the festival season; over the fifteen years they climb steadily as incomes rise; they sag for two or three years at a stretch when the wider economy slows, then recover; and they collapsed in April 2020 when a nationwide lockdown shut its showrooms.
