Answer 1

Answer:

(i) 336 and 782

336 to the nearest hundred = 300 and, 782 to the nearest hundred = 800

∴ Required sum = (300 + 800) = 1100

(ii) 546 and 342 and, 342 to the nearest hundred = 300

∴ Required sum = (500 + 300) = 800

(iii) 270 and 495

270 to the nearest hundred = 300 and, 495 to the nearest hundred = 500

∴ Required sum = (300 + 500) = 800

(iv) 4280 and 5295

4280 to the nearest hundred = 4300 and, 5295 to the nearest hundred = 5300

∴ Required sum = (4300 + 5300) = 9600

(v) 4230 and 2410

4230 to the nearest hundred = 4200 and, 2410 to the nearest hundred = 2400

∴ Required number = (4200 + 2400) = 6600

(vi) 30047 and 39287

30047 to the nearest hundred = 30000 and, 39287 to the nearest hundred = 39300

∴ Required sum = (30000 + 39300) = 69, 300
