Expert Answer:

For solving such problems we must keep an eye on the unit digits.

(a) 133, 698 and 867

Here the unit digits of the respective numbers are 3, 8 and 7 respectively. When you add the numbers with digits ending in 3 and 7, you get 10 or '0' at the units place.

Keep this in mind while attempting problem related to suitable arrangements.

(133 + 867) + 698

= 1000 + 698

= 1698
