The correct option is A 900
Given that Raj had ₹ 1398.
Amount spent on shopping = ₹ 526
Consider 1398, the tens digit 9 is greater than 5. Hence, on rounding off to the nearest hundred we get 1400.
Similarly, consider 526, the tens digit 2 is less than 5. So, 526 will be rounded off to 500.
Money left with him when estimated to nearest hundered will be
= ₹1400 - ₹500 = ₹900
