Question No 6

In the division calculation 952 473 Ã· 18, which two adjacent digits should be swapped in order to increase the result by 100?

Select the correct answer

9 and 5

5 and 2

2 and 4

4 and 7

Solution!

If after division by 18 the number has to be increased by 100, then before the division it needs to be increased by 18 Ã— 100 = 1800. So we need to find two adjacent digits in the number 952 473 which when swapped increase it by 1800. If 952 473 is increased by 1800 it becomes 952 473 + 1 800 = 954 273. We obtain 954 273 from 952 473 by swapping the adjacent digits 2 and 4.
