Estimate sum to the nearest thousand:
There are 54 balls in box A and 79 balls in box B. Estimate the total number of balls in both the boxes taken together.
Answer
Nearest thousand is 130. Solution:
The total number of balls in the both boxes is 54 + 79 = 133 balls.
Fill in the following boxes with the correct symbol > or <:
$47893501\ \Box\ 47894021$
Answer
$47893501<47894021$ Solution:
Both the numbers have the same digits, namely 4, 7, 8 and 9, at the crores, ten lakhs, lakhs and ten thousands places, respectively.
However, the digits at the thousands place in 47893501 and 47894021 are 3 and 4, respectively.
Clearly, 3 < 4
$\therefore 47893501 < 47894021$
