Greatest 7651 (digits descending); smallest 1567 (digits ascending).

Question 6

Arrange 2715, 2175, 2517 and 2157 in ascending order.

Accepted Answer

All have 2 thousands, so compare hundreds: 2157 < 2175 < 2517 < 2715.

Question 7

Add 216 + 3422 + 4019 + 497.

Accepted Answer

216 + 3422 = 3638; 3638 + 4019 = 7657; 7657 + 497 = 8154.

Question 8

Subtract 1348 from 3445.

Accepted Answer

3445 - 1348 = 2097, borrowing in the tens and hundreds.

Question 9

Multiply 56 by 43.

Accepted Answer

56 x 3 = 168. 56 x 40 = 2240. Total = 168 + 2240 = 2408.

Question 10

The sum of two numbers is 7036 and one of them is 3168. Find the other number.

Accepted Answer

Subtraction undoes addition, so the other number is 7036 - 3168 = 3868.

Question 11

Divide 543 by 6 and state the remainder. Check your answer.

6 into 54 goes 9 (54), remainder 0; bring down 3; 6 into 3 goes 0, remainder 3. So 543 / 6 = 90 remainder 3. Check: 90 x 6 = 540, and 540 + 3 = 543.

Accepted Answer

2100 + 3500 + 3200 = Rs 8800.
