Solution
The correct option is B 144
Every 8 days, Alex goes to market, and every 9 days, Shalini goes to market.
Let's find the common multiple of these days so that we can find out on which day they can meet in the market.
<Fill in the multiples of 8 and 9 in the venn diagram>
The common multiples of 8 and 9 are 72, 144, and so on.
Thus, they can meet on the 144th day.
