₹1228

Answer 2

1228

Step-by-step explanation:

In each city, Aswin spends `2 more than half of what he

has when he entered the city i.e., he is left with `2 less than

half of at the beginning. Therefore, when he entered each

city he has double of 2 more than what he had when he left

the city.

When he entered the third city he has 2(150 + 2) or 304

When he entered the second city he has 2 (304 + 2) or 612

When he entered the first city he has 2(612 + 2) or 1228
